Start with the G6's most underreported improvement: the anti-reflective coating. FlatpanelsHD measured panel reflectance at 0.3%, and found ambient light sources that were clearly visible on the G5 became substantially less intrusive on the G6. CNET found the same: overhead lights still register, but are far reduced. For anyone watching in a room with windows or ceiling lights, this is a meaningful quality-of-life upgrade, not a marginal spec improvement.

Shadow detail improved across both major reviews. FlatpanelsHD's darkest test scenes showed less dithering noise on the G6 than the G5. CNET found the G6 "demonstrably better" in that area. Two independent reviewers landing in the same place on a subjective quality is about as close to settled as TV reviewing gets.

The brightness picture is more nuanced. The 3,106-nit 2% window figure is the headline number, and it's real. But CNET found the G6 ran approximately 10% dimmer than the G5 in calibrated movie mode. FlatpanelsHD's 10% window measurement came in broadly in line with last year's model, not ahead of it. The improvement concentrates in small highlights and full-screen output. LG's "up to 20% brighter" claim is accurate in specific test conditions; it doesn't describe every measurement window.

Worth holding onto as context: Choose.tv noted in preliminary testing that the new Alpha 11 Gen3 processor's dynamic tone mapping may artificially elevate apparent brightness at the cost of image faithfulness in some scenes. That's preliminary and unconfirmed across all reviews, but it's relevant to the color accuracy question that follows.

The color story requires separating two things that are easy to conflate: gamut coverage and color behavior under real viewing conditions. Get them muddled and the review data looks contradictory. Keep them separate and the picture gets clearer.

On gamut coverage, the measurements are strong. FlatpanelsHD recorded 99.7% DCI-P3 coverage and 78.4% Rec. 2020 in HDR10 Filmmaker Mode, numbers they describe as outstanding, with calibration well within acceptable limits. Choose.tv measured 99.7% DCI-P3 on the G6 versus 99.6% on the G5, a difference that falls within measurement error. The data does not show a gamut regression.

What CNET observed is something different: the G6 struggles with accurate rendering of brighter colors and shows muted, degraded saturation when viewed off-axis. Gamut coverage tells you which colors a panel can produce. It doesn't tell you how accurately those colors are reproduced when the panel is pushed to high luminance, or how well saturation holds up at viewing angles outside the sweet spot. That gap is where the sources diverge.

Synthesizing the evidence, the regression appears most likely under stress conditions: high-luminance HDR scenes where aggressive tone mapping affects color volume, off-axis seating where the WOLED panel's angular characteristics reduce saturation, and out-of-box presets that prioritize brightness over fidelity. This is an interpretation of where the source data splits, not a confirmed lab result. In Filmmaker Mode, seated directly in front of the screen, the G6 measures well. Push the brightness, sit to the side, or leave the TV on a default preset, and CNET's observations suggest the G6 behaves less accurately than the G5 did.

For buyers, that distinction matters in a specific way. If you watch reference HDR content in Filmmaker Mode from the center seat, color performance will likely be excellent. Wider seating arrangements, Cinema or Standard presets for everyday viewing, or any color-critical use case: treat the G6 as a step back from the G5 in that dimension, and factor it into any comparison against a discounted G5.

The gaming package is thorough. All four HDMI 2.1 ports support the full modern gaming feature set, per FlatpanelsHD. The panel supports 4K at up to 165Hz for PC users, with Nvidia G-Sync and AMD FreeSync Premium, per TFTCentral. In Game Mode, FlatpanelsHD measured input lag at 10.8ms at 4K/60 and 5.3ms at 2K/120. At those numbers the latency stops being a variable most players will notice.

The footnote: CNET recorded 1080p latency of 13.57ms on the G6 versus 9.87ms on the G5 using Leo Bodnar testing. For most console and PC gaming at 4K or 1440p, that number is irrelevant. For competitive players running older titles at 1080p, it's a real step back, even if a small one. Gaming brightness improved over the G5, which matters more for most people playing in lit rooms than the latency regression does.

One connectivity point that affects a specific buyer: like the G5, the G6 does not support DTS decoding or DTS passthrough via eARC, per FlatpanelsHD. Owners with Blu-ray collections containing DTS soundtracks will need to route audio directly from their player to an external receiver, bypassing the TV entirely. Not a dealbreaker for most setups, but home-theater buyers at this price point should know going in.

LG's most substantive platform improvement is a commitment rather than a feature. The G6 comes with five years of webOS updates, and the five-year panel warranty is confirmed by both FlatpanelsHD and LG's own announcement. At $3,400 and up, that's a meaningful ownership assurance. It's one of the clearest ways LG has strengthened the long-term value case for flagship buyers.

The platform experience itself is a different story. WebOS 2026 is nearly indistinguishable from the 2025 version, per FlatpanelsHD. Menu navigation can feel sluggish, and FlatpanelsHD found voice queries taking over 30 seconds to return a response on their review unit. Generative AI tools are included and described as a novelty rather than a useful feature. These are findings from a single review unit and may vary, but the responsiveness complaints are specific enough to flag. WebOS ads remain in the interface, which sits oddly on a TV starting at $2,499.

Two omissions matter more for long-term buyers. First: the G6 will not support Dolby Vision 2, and LG has confirmed no firmware path to it, per FlatpanelsHD. This isn't an immediate picture-quality loss today, but the first DV2 content is expected in the second half of 2026, meaning buyers who hold the TV for several years will miss a format the next generation will support. Second: HDMI 2.2 is also absent, another forward-looking gap on a premium product. Neither blocks anything available now, but they're worth knowing before committing at this price.

The G6 is the strongest choice for viewers who watch in mixed or bright conditions, game regularly, or have found previous OLEDs too reflective for their setup. The 0.3% reflectance, improved shadow detail, and 3,106-nit small-highlight output are real gains, independently verified by CNET and FlatpanelsHD. For that buyer profile, the G6 makes one of the strongest current cases among premium OLEDs.

The G5 still has an argument, but a narrow one. A buyer who watches reference content in Filmmaker Mode, sits directly in front of the screen, and prizes color fidelity above daytime usability should price a discounted G5 seriously. The color accuracy award it earned doesn't disappear because a successor arrived.

Samsung's S95H represents a different set of priorities. It offers a wireless installation option, reaches roughly 2,930 nits on small highlights per CNET, comparable to where the G5 landed, and carries a feature set CNET describes as broader. Buyers who aren't tied to LG's ecosystem, or who want cable-free installation, should put the S95H on a direct comparison shortlist rather than treating the G6 as the automatic choice.

On value: at $3,399.99, the 65-inch G6 is a strong television. The price-to-performance case shifts noticeably if street pricing drops from that launch figure. At its current price the tradeoffs require careful evaluation; closer to $2,800, they become easier to accept. Choose.tv noted earlier this year that street-price trajectory would determine whether the G6 earns value-leader status in the premium segment. That observation still holds.

The G6 is a better TV for more rooms than the G5 was. It's also a measurably different TV from a color accuracy standpoint. Both things are true. Which one matters more depends entirely on where you watch.
