SAMSUNG S95F (TANDEM OLED 83") vs LG OLED B6

The Samsung S95F in the 83-inch variant with a Tandem OLED panel also enchants with its HDR effects. In test movie scenes, such as “Life of Pi” or “Sicario 2,” where smaller light points dominate – stars in the night sky, the glow of the moon, or headlights – the TV easily achieves brightness levels surpassing 2000 nits. This is a result that not long ago seemed unattainable for OLEDs and places this model in the same category as the best Mini-LED constructions.

The limitations of organic panels only emerge in full-screen scenes completely filled with white. In the case of this model, for example, in the final scene of the film The Meg, brightness drops to around 1000 nits – slightly lower than in the smaller QD-OLED variants, where the result hovered around 1400 nits. Nevertheless, we are still talking about an outstanding result, unprecedented in OLED TVs of this size. The colour reproduction is equally impressive. The new Tandem OLED panel nearly catches up to QD-OLED TVs, offering excellent coverage of a wide colour gamut. The results are slightly weaker than those of QD-OLED, but in practice, they still provide an image whose intensity and naturalness of colours are hard to compare with any other television.

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.

The best picture mode right out of the box is undoubtedly Filmmaker Mode. This mode has been present in Samsung televisions for several years and is intended to reproduce the image as faithfully as possible to the creators' vision. In SDR material, it performs reasonably well, though not without flaws. The image is slightly dimmed, and the white balance tends to shift towards red and blue, resulting in a slight pinkish tint on the screen. Average colour errors hover around values of ΔE 3–4, which is on the borderline of what most people can detect with the naked eye.

The limitations are much more apparent with HDR content. Here, a slight excess of blue in the white balance isn't such a big issue – the real obstacle is how the television manages brightness. In many scenes, the image looked as if it had been blown out, and details in the blacks could completely vanish. The final effect didn't do justice to what such a device is capable of, leading to significant colour inaccuracies. It's hard to understand why such a factory characteristic was chosen, as the perception of HDR in this rendition was definitely not what it should have been.

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.

After calibration, the S95F shows what it can really do. The white balance has been straightened out, and minor inaccuracies have been corrected, making the image in SDR content look nearly exemplary. Colour differences have fallen below the level that the human eye can detect – looking at the screen, one just gets the impression of complete naturalness and harmony of colours.

In HDR, the improvement is equally noticeable. The TV handles brightness much better, and there’s no longer the 'blowing out' of the entire frame. Bright scenes are more controlled, and blacks retain more detail, though sometimes a slight brightening of the overall image can still be noticed. However, this doesn’t change the fact that after calibration, the S95F delivers an image that can confidently be called one of the best on the market – regardless of whether we’re watching movies in SDR or spectacular productions in HDR.

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.

The Samsung S95F model features noise reduction, aimed at improving the fluidity of tonal transitions. Its effectiveness is difficult to call ineffective – on the contrary, it can excessively interfere with the image. Older films or materials of lower quality, such as those from YouTube, take on a soft, smoothed character reminiscent of a painting effect thanks to this feature. The problem is that along with the noise, the natural film grain, which gives the image a cinematic quality, also disappears. Fortunately, the feature does not blur significant details, so its use is more a matter of preference. If someone prefers a slightly polished and smooth image, it’s worth turning it on, but in our opinion, the most sensible setting is “Standard”.

Upscaling leaves a better impression. The S95F efficiently enhances the quality of lower resolution content – even 576p videos look quite good, although minor artifacts in the form of blockiness can be noticed. Overall, the effect is very solid, although when compared to the competition – such as the Sony Bravia 8 (II) or LG G5 – it is noticeable that those models can extract a bit more from the image. However, one inconvenience to remember is that in the case of older films and photos, there is a problem with overscan, which causes a slight trimming of the left edge of the image.

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.

In the case of the 83-inch S95F with a Tandem OLED panel, the fluidity of motion also makes a huge impression. The panel in native 4K resolution offers a refresh rate of 165 Hz, and this combined with organic technology makes games and sport look fantastic. Additionally, the manufacturer has added a motion smoother and a motion blur reduction system, allowing each viewer to customise the picture to their own preferences – whether a more 'choppy', cinematic effect or a smooth, almost theatrical spectacle.

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.

Low motion blur and phenomenal motion fluidity, hallmarks of the OLED panel, are just the warm-up. The Samsung S95F has been designed with gamers in mind – and this is evident at every turn. Four HDMI 2.1 ports with a bandwidth of 40 Gb/s may sound like a compromise on paper, but in practice, neither consoles nor PCs will feel the slightest limitation here. Onboard is a full set of gaming features: variable refresh rate VRR, automatic game mode ALLM, and an excellently implemented HGiG standard, which allows you to enjoy HDR exactly as the creators intended. All this is complemented by Game Bar – an intuitive command centre where you can check and adjust the most important settings in seconds.

Particularly noteworthy is Game Motion Plus, Samsung's proprietary motion smoother. It can add additional fluidity to animations, which can be a lifesaver in games running at 60 frames, where stability doesn't always hold up. Yes, there's no support for Dolby Vision in games, but it's hard to consider this a serious flaw – the manufacturer compensates for this gap with other solutions. The S95F is one of the absolute favourites for the title of the best gaming television on today's market.

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.
