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

The Samsung S95F in the 83-inch variant with a Tandem OLED panel also manages to enchant with HDR effects. In test film 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 television effortlessly achieves brightness values exceeding 2000 nits. This is a result that not long ago seemed unattainable for OLEDs and positions this model alongside the best Mini-LED constructions.

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

The 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 the new, budget OLED SE panel from LG Display. In practice it simply gives a bit more headroom and makes HDR look fuller in many scenes than on last year’s lower‑end OLEDs. That does not mean the B6 has no limitations. In very bright shots, when a large part of the screen is strongly lit, brightness can fall below 400 nits. This behaviour is typical for OLED TVs, especially in this segment, and that’s where you see the biggest difference compared with more expensive models. Even so, we judge the B6’s results as genuinely solid. It’s still not a TV for breaking brightness records, but the HDR effect is strong enough that films truly feel like a step up from ordinary SDR. Colour gamut Using the OLED SE panel has had a slight impact on wide colour gamut coverage. Compared with last year’s model the results have fallen by a few percentage points. It covers roughly 96% of DCI‑P3 and about 71% of BT.2020. That doesn’t mean the colours on the LG B6 are weak. In most films and series they look lively, 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 stems from the WOLED panel structure. Besides red, green and blue subpixels it also uses a white subpixel, which helps to boost brightness. However, this comes at a price. At very high luminance some colour is effectively 'diluted' by the white light, so the saturation of certain colours can be slightly lower. In everyday use this isn’t a major issue, but in the most demanding scenes you can notice it.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode. This is a mode that has been available 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, although not without faults. The image is slightly subdued, and the white balance tends to shift towards red and blue, resulting in a slight pinkish tint on the screen. The average colour errors hover around a value of ΔE 3–4, which is at the limit of what most people can discern with the naked eye.

Much more pronounced are the limitations when it comes to HDR content. Here, a slight excess of blue in the white balance is not such a big problem – the real obstacle is the way the television manages brightness. In many scenes, the image appeared as if it had been overexposed, and details in the blacks could completely disappear. The final effect did not reflect what the hardware of this class is capable of and led to significant colour errors. It's hard to understand why such a factory characteristic was chosen, as the HDR reception in this version 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 produce very similar results, but in our tests we always stick to Filmmaker Mode for better comparison with other TVs. Each of them is, in any case, a much better starting point than Vivid or Eco mode, where the picture is heavily boosted and noticeably less natural. On SDR material the factory settings perform really well. Colour errors are small, the gamma response is correct, and the picture during normal viewing looks natural and does not feel overly "pumped up". It's a bit worse with HDR. When such content is played you quickly see that the white balance hasn't been set perfectly. Too much blue and red gives the image a slightly pink tint. This is also confirmed by colour gamut measurements and the ColorChecker, where samples clearly shift in that direction. It's not a flaw that completely spoils the picture, but it is noticeable with HDR films. Therefore anyone who wants the most faithful image should consider calibration, which we cover further on in the review.

After calibration, the S95F shows what it is truly capable of. The white balance has been corrected and minor inaccuracies adjusted, resulting in an almost exemplary image for SDR content. The colour differences have dropped below the level that the human eye can perceive – looking at the screen gives a sense of complete naturalness and colour coherence.

In HDR, the improvement is equally noticeable. The TV performs much better with brightness, eliminating the issue of "blowing out" the entire frame. Bright scenes are more controlled, and blacks retain more detail, although there can still be a slight brightening of the image as a whole. However, this does not change the fact that after calibration, the S95F delivers an image that can comfortably be called one of the best on the market – regardless of whether we are watching movies in SDR or spectacular productions in HDR.

During calibration, we concentrated mainly on HDR content, because that's where the factory settings needed the most correction. We did not, however, neglect SDR mode, which after adjustment was brought almost to perfection. Colours are very accurate, and brightness is controlled as it should be. The biggest improvement in HDR came from fixing the white balance. Removing the excess red and blue eliminated the pinkish tint, and the image became much more natural. Skin tones, whites and all colours that had previously shifted towards pink 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. So the LG B6 can deliver a very accurate picture, particularly for the manufacturer's entry-level OLED model.

In the Samsung S95F model, there is a noise reduction feature aimed at improving the smoothness of tonal transitions. Its operation can hardly be called ineffective – on the contrary, it can overly interfere with the image. Older films or materials of poorer quality, such as those from YouTube, acquire a soft, smoothed character thanks to it, reminiscent of a painting effect. The problem is that along with the noise, the natural film grain disappears, stripping the image of its cinematic character. Fortunately, the feature does not blur significant details, so its use is more a matter of taste. If someone prefers a slightly polished and smooth image, it is worth enabling, but in our opinion, the most sensible setting is “Standard”.

A better impression is left by the upscaling. The S95F efficiently enhances the quality of lower resolution content – even 576p video looks quite good, although minor artifacts in the form of blockiness can be noticed. Overall, the effect is very solid, although when compared to competitors – 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, it is worth remembering one inconvenience: with older films and photos, there is an overscan issue that causes a slight cutting off of the left edge of the image.

The LG B6 handles lower-quality material very well. This is largely thanks to effective digital image processing, which can mask some of the source’s imperfections without overly smoothing the whole scene. The "Smooth Gradation" function proves particularly useful. It noticeably reduces posterisation, especially in dark parts of the image. The safest choice remains the Low or Medium setting. The function still effectively smooths out unsightly tonal banding, but does not yet interfere too much with fine details. Purists can of course leave it switched off. Upscaling to 4K also performs very well. Full HD and 720p material retain a good amount of detail, and the image is neither overly sharpened nor heavily blurred. Some limitations only become apparent with very poor sources below 720p, where the smallest text and fine elements are not always perfectly sharp, but this applies to 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, with a native resolution of 4K, offers a refresh rate of 165 Hz, and this combined with organic technology makes games and sports look superb. Additionally, the manufacturer has added a film smoother and a motion blur reduction system, allowing each viewer to adjust the image to their own preferences – whether it's a more "frame-rate" cinematic effect or a smooth, almost theatrical spectacle.

One of the biggest advantages of OLED panels is the very fast pixel response time. This keeps the picture sharp and free of the visible smearing often seen on LCD TVs. However, there is a downside. During slow camera pans motion can look choppier than on LCD screens, where some of that effect is naturally masked by the slower panel. Fortunately, on the LG B6 this can be easily mitigated using the TruMotion system. With the motion smoothing set correctly you can achieve smoother motion without giving the picture an exaggerated soap opera effect.

Low smearing and phenomenal motion fluidity, which are the hallmarks of OLED displays, 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 experience the slightest limitation here. On board, there is a full set of gaming features: Variable Refresh Rate (VRR), Auto Low Latency Mode (ALLM), as well as a flawlessly implemented HGiG standard that allows you to enjoy HDR exactly as the creators intended. All of this is complemented by Game Bar – an intuitive command centre where you can check and adjust the most important settings in seconds.

Particular attention should also be paid to Game Motion Plus, Samsung's proprietary motion smoothing technology. It can add extra fluidity to animations, which can be a lifesaver in games running at 60 frames per second, where stability doesn't always hold up. Indeed, support for Dolby Vision in games is lacking, 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 to offer gamers; it’s simply a complete base for PS5, Xbox Series X/S or a capable PC. It has four full-size HDMI 2.1 ports with 48 Gbps bandwidth, so you can avoid irritating cable swapping when connecting several newer devices at once. It offers a full suite of synchronization technologies, from standard VRR to G-Sync and FreeSync. The screen synchronises the refresh rate seamlessly with the frame output from the console or graphics card. Of course it includes ALLM: the B6 automatically recognises when a game is running and immediately reduces latency to a minimum. HDR support is also excellent. The TV supports Dolby Vision, and a correctly implemented HGiG standard means that, after initial calibration in the console settings, the image won’t suffer from blown-out highlights or lost detail in bright areas. The cherry on the cake is the Game Bar. Instead of digging through the full menu during gameplay, a single click is enough to adjust shadow visibility, tweak selected parameters or simply check the current display mode. All of this makes the LG B6 an excellent choice for gamers.
