Sony Bravia 8 MK2 vs LG OLED B6

Thanks to its new QD-OLED panel, the Sony Bravia 8 II can reach an astronomically high brightness of around 2000 nits, which translates into near-reference quality for movies and series mastered in HDR. In test material like Life of Pi or Sicario 2 the effect is simply stunning, with details in bright areas remaining perfectly visible and nighttime scenes impressing with depth and contrast. It is not perfect, though. Compared with its toughest rivals, the Bravia 8 II shows a noticeable drop in brightness on full-screen, very bright frames. If you compare peak spot luminance with 100% white luminance in HDR mode, the Bravia 8 II can appear two to three times dimmer than the LG G5 or Samsung S95F models. In the scene from The Meg this was especially apparent, as the screen became noticeably dimmer than competing TVs. Despite this shortcoming, the Bravia 8 II’s results still place it among the market leaders. Its absolutely top-tier color gamut coverage deserves praise, with DCI-P3 at nearly 100% and BT.2020 close to 90%. These figures let HDR content reach its full potential and deliver cinema-like experiences at home.

The LG B6 is a moderately bright OLED. After calibration it reaches about 800 nits, roughly 200 nits more than last year’s B5. That’s thanks to the new budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR in many scenes look fuller than on last year’s lower-tier OLEDs. That doesn’t mean the B6 has no limits. In very bright shots, when a large part of the screen is strongly lit, brightness can drop below 400 nits. This behavior is typical for OLED TVs (especially those from this segment) and that’s when you see the biggest difference versus more expensive models. All things considered, we rate the B6’s results as really solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that you can really feel the step up from ordinary SDR in films.

Color gamut

Using the OLED SE panel has slightly affected wide color gamut coverage. Compared with last year’s model, results fell by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn’t mean the colors on the LG B6 are weak. In most movies and series they look lively, well saturated and simply pleasing to the eye. You only notice a difference in very bright, highly colorful scenes. Then colors lose some intensity compared with QD-OLED panels. This comes from the WOLED panel construction. Besides red, green and blue subpixels it also uses a white subpixel that helps boost brightness. It comes at a cost: at very high luminance some color is effectively “diluted” by the white light, so saturation of some colors can be slightly lower. In everyday use this isn’t a big issue, but you can notice it in the most demanding scenes.

Out of the box the Bravia 8 II performs really well. In its best IMAX® Enhanced mode the TV renders colors pleasantly and naturally, though "good" here doesn't mean "best in class." The white balance definitely needs adjustment, as skin tones tend to shift slightly toward pinkish/cooler hues in both SDR and HDR content. We also noticed that the EOTF curve has a tendency to brighten the darkest parts of the picture. This likely comes from the manufacturer's desire to reveal as much detail as possible even in deep shadows. Is that a good approach? It's hard to say for sure, but one thing is clear: it's not an ideal solution.

We tested the LG B6 in Filmmaker Mode, which is the best picture setting available right out of the box. ISF modes deliver very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of those modes is, after all, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. With SDR content, the factory settings perform really well. Color errors are small, gamma behaves properly, and the image looks natural during ordinary viewing and does not seem overly "pumped up." It's a bit worse with HDR. When you play that kind of content you can quickly see that the white balance hasn't been set perfectly. Too much blue and red causes the image to shift toward a slightly pink tint. This is also confirmed by measurements of the color gamut and the ColorChecker, where samples clearly drift in that direction. It's not a flaw that completely ruins the picture, but you can notice it in HDR films. So people who care about the most faithful image should consider the calibration we describe later in the review.

After calibration we mainly managed to eliminate the excessive cooling of the image caused by too strong a boost in blue. Reds became deeper and skin tones took on a natural, healthy look. Actors who had previously seemed "cold" now appear on screen much livelier and more convincing. One thing hasn't changed, however: analysis of the EOTF curve still shows the Bravia 8 II tends to brighten the darkest parts of the image. It's hard to say whether that's an intentional choice by the manufacturer or a result of the panel design and software. In practice this means scenes that filmmakers intended to remain in deep shadow can reveal more detail than intended. Despite that, the picture after calibration is clearly better — warm, natural colors and realistic skin tones simply make watching on the Bravia 8 II more pleasant to the eye.

During calibration we focused primarily on HDR content, because that's where the factory settings required the biggest corrections. We didn't neglect SDR mode, though, which after adjustment was brought almost to perfection. Colors are very accurate and brightness is handled as it should be. The biggest improvement in HDR came from correcting the white balance. After removing the excess red and blue, the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colors that had been shifting toward magenta improved. After calibration most errors fell below a Delta E of 2–3, the threshold at which the average viewer stops noticing differences with the naked eye. The LG B6 can therefore deliver a very accurate image, especially for the manufacturer's entry-level OLED model.

Upscaling and digital image processing are a real showcase for the Bravia 8 II. Sony has long been regarded as a master in this field, and this only reinforces that reputation. The company's proprietary XR processor can extract almost the maximum from lower-resolution sources, whether broadcast TV or an old DVD, the picture looks sharper, with more detail and better depth. Sure, if you feed it exceptionally poor-quality material (like our archival photo of the model), you won't get miracles, but for everyday viewing there's little to complain about.

The smooth gradation feature also performs very well. On the "Medium" setting it effectively smooths tonal transitions, eliminating banding in color and gray gradients while preserving film grain and fine image detail. It's precisely that balance between subtlety and effectiveness that keeps Sony TVs among the best on the market in this category.

The LG B6 handles lower-quality sources very well. Much of the credit goes to effective digital image processing, which can mask some source imperfections without overly smoothing the whole scene. The feature "Smooth Gradation" proves particularly useful. It can significantly reduce posterization, which we mentioned earlier, especially in darker areas of the image. The safest choice remains Low or Medium. The function still effectively smooths harsh tonal transitions, but does not yet interfere too much with fine details. The most dedicated purists can, of course, leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a good amount of detail, and the image is neither overly sharpened nor excessively blurred. Some limitations become noticeable only with very poor sources below 720p, where the smallest subtitles and fine elements are not always perfectly sharp, but this is true for almost every other TV on the market.

When it comes to motion handling, the Bravia 8 II is basically a done deal. The OLED panel with a 120 Hz refresh rate naturally delivers a very clean, sharp picture in fast-moving scenes, so there's little to complain about. What deserves special praise, though, is one of the best motion smoothing systems on the market. It lets you precisely tailor motion in films to your preferences, from subtle smoothing to an almost "theatrical" look, without the risk of artificial judder, image tearing, or annoying artifacts. It's one of those features you'll appreciate both when watching movies and during sports.

One of the biggest advantages of OLED panels is their very fast pixel response time. This keeps the image sharp and prevents the visible smearing that often appears on LCD TVs. However, there is a downside. During slow camera pans, motion can look more choppy than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 you can easily soften this with TruMotion. With the motion smoothing properly adjusted, you can achieve smoother motion without giving the picture an excessive soap-opera effect.

Sony really learned from previous years, and with the Bravia 8 II it has put together a package of gamer-focused features that’s hard to call anything but "almost perfect." It includes everything you expect at this level: VRR, ALLM, Dolby Vision Gaming mode, HGiG, and even a handy Game Bar that lets you quickly check parameters and change settings without leaving the game. Also a plus is how smoothly and seamlessly these features work, with no delays and no odd stuttering. You just launch a game and everything looks as it should. Unfortunately, it’s not without a few caveats. The manufacturer still gives us only two full-bandwidth HDMI ports, so if you have a console, a PC, and another device like a soundbar connected via eARC, you’ll be swapping cables. It’s also surprising there’s no support for 1440p at 120 Hz, which is particularly important for Xbox players. Overall, though, this is one of those TVs you can comfortably place at the center of a gaming-focused living room and enjoy gameplay without major compromises.

LG OLED B6 offers a powerful set of advantages for gamers; it's simply a complete platform for PS5, Xbox Series X/S, or a solid PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can skip the annoying cable swapping when you want to connect several newer devices at once. We get the full suite of sync technologies – from classic VRR to G-Sync and FreeSync. The screen seamlessly matches the refresh rate to the frame output produced by the console or graphics card. Of course ALLM is included: the B6 automatically detects a running game and immediately cuts input lag to a minimum. HDR handling is also excellent. The TV supports Dolby Vision, and a properly implemented HGiG standard means that after an initial calibration in the console settings the picture won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on top is the Game Bar. Instead of digging through the full menu during gameplay, one click lets you adjust shadow visibility, tweak selected settings, or simply check the display’s current operating mode. All of this makes the LG B6 a great choice for gamers.
