- Better full-screen brightness and improved reflection handling
- More accurate contrast with deeper, cleaner blacks
- Richer and more natural color reproduction
- Stronger, fuller built-in sound performance
LG’s G-series OLED TVs have consistently set a high bar, and last year’s G5 was already among the best you could buy. It combined excellent contrast, vibrant colors, and top-tier gaming features into a premium but worthwhile package. So expectations for its successor were understandably high.
After putting the new G6 through side-by-side testing with the G5 using reference 4K Blu-rays, the differences quickly became clear. This is not a radical reinvention, but a thoughtful refinement that improves picture accuracy, brightness balance, and overall viewing experience in ways that actually matter.
Brighter, but more controlled
On paper, the G6 delivers a modest boost in peak HDR brightness. In practice, the real improvement shows up in full-screen brightness, where the G6 makes a significant leap. This means brighter, more consistent images in scenes that fill the screen, such as snowy landscapes or daylight sequences.
What stands out, though, is restraint. The G6 avoids pushing brightness too aggressively. Where the G5 can sometimes look overly vivid or slightly blue in bright scenes, the G6 opts for a more natural balance. Whites look cleaner and more accurate rather than artificially boosted.
Another major win is reflection handling. The G5’s glossy screen can struggle in well-lit rooms, with mirror-like reflections distracting from the image. The G6 reduces this significantly. Even if it appears slightly dimmer in some situations, the cleaner image makes it far easier to watch in bright environments.
Contrast that feels more authentic
OLED TVs are known for deep blacks, and both models perform strongly here. However, the G6 takes things a step further with more refined contrast.
In darker scenes, the G6 produces deeper blacks without crushing detail. The G5, by comparison, can slightly lift dark tones, which makes the image appear brighter but less accurate. The difference is subtle but noticeable, especially in films with heavy shadow detail.
Highlights also benefit from this balance. Bright elements such as lamps or reflections stand out more naturally against darker backgrounds. The result is an image that feels more cinematic and less processed.
Shadow detail remains excellent on both sets. The G5 may reveal slightly more in some dark areas, but the G6 strikes a better balance between visibility and realism.
Color tuning that favors realism
The most noticeable difference between the two TVs comes down to color. At first glance, the G5’s colors may seem more eye-catching because they are brighter and more saturated.
But spend more time with both, and the G6 clearly pulls ahead. Its colors are richer, more nuanced, and far more lifelike. Reds, greens, and blues all show greater depth without looking exaggerated.
Skin tones are a particularly strong improvement. On the G5, they can occasionally lean too red. The G6 corrects this, delivering more natural and consistent tones across different lighting conditions.
This more restrained color approach pays off across all types of content. Whether it is live-action films or animation, the G6 presents a more balanced and believable image.
Improved sound, but still not a replacement
Audio is another area where LG has made subtle but meaningful changes. The G6’s built-in sound is fuller and more forward, with stronger bass and a warmer tone overall.
Dialogue remains clear, and sound positioning is accurate on both models. However, the G6 adds more impact, especially in action scenes where low-end presence makes a noticeable difference.
That said, neither TV replaces a dedicated sound system. A good soundbar will still elevate the experience significantly.
The verdict: refinement done right
The G6 does not reinvent the formula, but it does refine it in all the right places. It improves brightness where it counts, enhances contrast without exaggeration, delivers more accurate colors, and handles reflections far better.
The G5 remains an excellent TV and is likely to be the better value option as prices drop. But if you are looking for the most polished and balanced OLED experience, the G6 stands out as the more complete package.
