LG OLED B6 vs Sony BRAVIA 7 II

LG B6 is a moderately bright OLED. After calibration it reaches around 800 nits, roughly 200 nits more than last year's B5. That's down to LG Display's new budget OLED SE panel. In practice this simply provides a bit more headroom and makes HDR look fuller in many scenes than on last year's lower-end OLEDs. That doesn't mean the B6 has no limitations. In very bright shots, when a large part of the screen is brightly lit, brightness can fall below 400 nits. This behaviour is typical of OLED TVs (especially in this segment), and it's then you see the biggest difference compared with pricier models. All the same, we rate the B6's results as really solid. It's still not a TV built to break brightness records, but the HDR effect is strong enough that films really feel like a step up from ordinary SDR picture.

Colour gamut

Using the OLED SE panel has had some impact on wide colour-gamut coverage. Compared with last year's model the figures have dropped by a few percentage points. DCI-P3 reaches about 96%, and BT.2020 around 71%. That doesn't mean the colours on the LG B6 are weak. In most films and TV series they look vivid, well saturated and simply pleasing to the eye. You only notice the difference in very bright, highly colourful scenes. Then colours lose some intensity compared with QD-OLED panels. This is due to the WOLED panel structure. In addition to the red, green and blue subpixels it also uses a white subpixel that helps boost brightness. This comes at a cost: at very high luminance some of the colour is effectively 'diluted' by the white light, so saturation of some hues can be slightly lower. Day-to-day it's not a big problem, but you can see it in the most demanding scenes.

Sony Bravia 7 II handles HDR very well and, above all, is simply a bright television. In the correct viewing mode for watching, Professional, we measured about 2,000 nits of peak brightness, so the panel’s capabilities are truly large. Of course, in Mini-LED sets a test-pattern result is only part of the story, because much still depends on how the TV controls the backlight in real scenes. Here Sony’s algorithms perform really well. Depending on the scene, the brightness we measured in films ranged from about 1,100 to as much as 1,700 nits. That’s a level at which HDR has proper punch and bright highlights can be genuinely impressive. It’s not perfect in every situation. With small bright elements on a very dark background, the Bravia 7 II clearly prioritises maintaining good black levels, so their brightness can fall to around 500 nits. It still looks good, but it’s clear the TV doesn’t always manage this without compromise.

Colours

The second thing that has a huge impact on HDR is, of course, colour. And this is where True RGB was meant to deliver one of the biggest changes. Looking at the panel’s capabilities alone, the Bravia 7 II performs very well. We measured roughly 98% DCI-P3 coverage and 88% BT.2020, so the potential for showing highly saturated colours is substantial. In RGB TVs the matter is a bit more complex. When we repeated the same measurements with a film-like background applied, gamut coverage dropped to about 92% DCI-P3 and 78% BT.2020. Those are still good numbers, especially for an RGB Mini-LED TV, but they show that the final result largely depends on how the algorithms drive the three backlight colours. In most scenes the Bravia 7 II handles this well and colours retain strong saturation. The biggest differences are visible in blue shades, where samples start to deviate more noticeably from the reference values and coverage is weaker than for the other primaries. True RGB therefore offers genuinely greater potential, but, as with brightness, a lot depends on what’s actually happening on screen.

We tested the LG B6 in Filmmaker Mode, the best picture setting available straight out of the box. ISF modes give very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is a far better starting point than Vivid or Eco, where the picture is heavily boosted and noticeably less natural. For SDR content the factory settings perform really well. Colour errors are small, gamma behaves correctly, and the picture looks natural during regular viewing and does not seem overly enhanced.

It's a bit worse with HDR. Once you start playing that kind of content it's quickly apparent the white balance isn't perfectly set. Too much blue and red makes the image take on a slightly pink tint. Colour gamut measurements and the ColorChecker confirm this, with samples clearly shifting in that direction. It's not a defect that completely ruins the picture, but you can notice it with HDR films. So anyone who wants the most faithful image should consider calibration, which we cover later in the review.

To evaluate the factory colours we chose the Professional mode, because it performs best among the available presets. It's not perfect. In SDR the white balance is slightly biased toward magenta, so some scenes look a little warmer and less neutral than they should. A bigger issue is the gamma, which sits closer to 2.5 than 2.4. As a result the image is a bit too dark in places, especially in the mid-tones. In HDR the situation is better. As brightness increases there's a little too much red, but it isn't something that really jumps out while watching. Overall the Professional mode is a good starting point, though you can get a bit more out of it with calibration.

During calibration we focused mainly on HDR material, because that’s where the factory settings needed the most correction. We didn’t neglect SDR, though. After tuning it was brought almost to perfection. Colours are very accurate and brightness is controlled as it should be. The biggest change in HDR came from improving the white balance. After removing excess red and blue the pinkish tint disappeared and the image became much more natural. Skin tones, whites and all colours that had previously leaned towards pink improved. After calibration most errors fell below Delta E 2-3, the threshold at which an average viewer stops noticing differences with the naked eye. So the LG B6 can produce a very accurate picture, especially for the manufacturer’s entry-level OLED model.

After calibration the Bravia 7 II can look significantly better. First and foremost, we managed to set the white balance very well in both SDR and HDR. Gamma can also be improved, and after correction it runs very close to the reference value. For most users those changes will have the biggest impact on the picture. There is, however, a limitation with the colours themselves. On the Bravia 7 II Sony does not provide access to a traditional CMS that would let us adjust individual hues separately. Much is left to the algorithms controlling the True RGB backlight. If the TV reproduces a specific colour inaccurately, we are not always able to do anything about it. In our measurements this is most apparent in parts of the reds and blues, where errors can still be quite large. That does not, however, undermine the value of calibration. Correctly setting the white point and gamma strongly affects the whole picture, so even without the ability to precisely correct every colour the difference from the factory settings is noticeable.

LG B6 copes very well with lower-quality material. Much of that is down to effective digital image processing, which can mask some source imperfections without excessively smoothing the whole scene. The "Smooth Gradation" feature proves particularly useful. It lets you noticeably reduce posterization mentioned earlier, especially in dark parts of the image. The safest choice is to set it to Low or Medium. The feature still effectively smooths out harsh tonal transitions, but doesn't yet interfere too much with fine details. Die-hard purists can of course leave it off. Upscaling to 4K also performs very well. Full HD and 720p content retain a fair amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations are only noticeable with very poor sources below 720p, where the smallest text and fine elements aren't always perfectly sharp, but this is true for almost every other TV on the market.

Scaling and digital processing are among the strongest points of the Bravia 7 II and one of Sony's biggest advantages over the competition. Sony has for years excelled at digital image processing, and it's clear here too. Above all, the 'Smooth Gradation' function works very well, smoothing weaker tonal transitions in poorer-quality content. The safest setting is low, but we'd comfortably recommend medium as well. The effect is stronger, and the TV still handles fine detail very delicately. Some minor details may be slightly smoothed, but Sony does it much more subtly than many other brands. Upscaling is also very good. Lower-resolution content is nicely upscaled to 4K; the image looks clean and retains a lot of detail. Of course the TV won't magically turn native HD into true 4K, but the Bravia 7 II does very well with what can be pulled from such a source.

One of the biggest advantages of OLED panels is their very fast pixel response time. That keeps the picture sharp and prevents visible smearing that often appears on LCD TVs. It does have a downside, though. During slow camera pans motion can look a bit choppier than on LCD screens, where the slower panel naturally masks some of that effect. Fortunately, on the LG B6 this is easy to tame with TruMotion. With the motion smoothing set correctly you can get smoother motion without giving the picture an exaggerated soap-opera effect.

The Bravia 7 II uses a 120 Hz panel, so in terms of motion handling it delivers everything you'd expect from a TV of this class. With sport or games at 120 fps the picture is suitably smooth, and for films Sony provides an advanced motion interpolation system. You can therefore adjust the level of interpolation separately and choose whether to retain a more cinematic motion or achieve noticeably greater smoothness. Motion blur itself is a bit worse. The VA panel used isn't among the fastest, and moving objects can show a slight trailing, especially against darker backgrounds. It's not at a level that will seriously disturb normal viewing, but last year's Bravia 7 was better in this regard and had a noticeably faster panel.

LG OLED B6 has plenty going for gamers; it's a complete base for the PS5, Xbox Series X/S or a solid PC. It comes with four full-size HDMI 2.1 ports with 48 Gb/s bandwidth, so you can forget about annoying cable swapping when you want to connect several newer devices at once. We get a full package of sync technologies, from classic VRR to G-Sync and FreeSync. The panel effortlessly syncs its refresh rate to the frame pacing produced by your console or graphics card. Of course ALLM is present: the B6 automatically recognises when a game is running and immediately cuts latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG means that after an initial calibration in the console settings the picture won't suffer from blown-out whites or lost detail in bright areas. The icing on the cake is the Game Bar. Instead of digging through the full menu mid-game, a single click lets you correct shadow visibility, tweak chosen parameters or simply check the display's current mode. All of this makes the LG B6 a great choice for gamers.

Bravia 7 II has pretty much everything you'd want from a good console TV today. It supports 4K at 120 Hz, VRR from 48 to 120 Hz and ALLM, so when you start a game the TV automatically switches to low-latency mode. HGiG works correctly, so once you configure HDR on the console the TV won't try to brighten the image on its own. Just remember to turn off tone mapping in the TV's menu. Another plus is Dolby Vision in game mode, which will be especially useful for Xbox owners. Sony also includes its own Game Menu, where you can quickly view key signal info, check VRR or change gaming settings without digging through the full TV menu. The only thing missing from the feature list is support for 1440p at 120 Hz. Our biggest complaint is not really about the features but the connectors. The Bravia 7 II has four HDMI ports, but only two of them support full HDMI 2.1 with 48 Gbps bandwidth. One of those is also the eARC port. So if you connect a soundbar or AV receiver via HDMI, in practice you only have one full HDMI 2.1 left for a console or PC. With a single console that's fine, but with a PS5, an Xbox and an audio setup it starts to feel cramped. That's hard to justify from Sony. In cheaper TVs two HDMI 2.1 ports can still be accepted, but in a model of this class, especially in 2026, we'd expect all four ports to be HDMI 2.1.
