SAMSUNG OLED S95F (QD-OLED) vs LG OLED G6 (G64LW, G66LS)

The new generation of QD-OLED panels in Samsung's S95F showcases its full potential, and the brightness results are simply astounding. In test film scenes, such as “Life of Pi” or “Sicario 2”, where smaller light elements appear – stars, the moon, or spotlights – the television managed to achieve over 2000 nits of brightness. This is a result that surpasses even most top Mini-LED models.

The secret lies in the technology itself – instead of a limited number of dimming zones like in Mini-LED televisions, here we have millions of glowing pixels, allowing the television to fully demonstrate its power without technological compromises. Of course, since it is still an organic panel, in scenes that are full-screen and flooded with white – like in the final sequence from The Meg – brightness drops to around 1400 nits. Nevertheless, the result remains excellent and definitely exceeds what any OLEDs, both QD-OLED and WOLED, have offered so far. The colour reproduction is also particularly noteworthy. Thanks to QD-OLED technology, the television achieves almost 100% coverage of the DCI-P3 colour space and around 80% in BT.2020. These values make HDR images not only dazzling in brightness but also stunning in their range of colours.

The LG G6 is currently one of the brightest OLEDs on the market. Its peak brightness reaches nearly 2500 nits and, best of all, this translates directly to real movie scenes. The TV flawlessly extracts details in the bright areas of the image. And this is regardless of whether we are talking about very small points in the form of stars in the sky or slightly larger elements on the screen. Naturally, with full-screen, uniformly white scenes, the brightness of the G6 drops due to the panel protection system (ABL). However, in real, varied movie shots, this value still hovers around an impressive 2000 nits, which can be considered a remarkable result. The coverage of the color palette also deserves praise. The new 2nd generation Tandem OLED panel has brought about only a cosmetic change, but still an improvement. The coverage of the DCI-P3 color space reaches nearly 99.5%, while the ultra-wide BT.2020 is around 84%. These are very good results, although it's important to remember one thing: at extremely high brightness levels, the volume of colors will be lower than in QD-OLED panels from Samsung Display due to the use of white sub-pixels (WOLED). However, in everyday content and most films, capturing this difference will be very difficult.

The best picture mode straight out of the box is undoubtedly Filmmaker Mode – a mode that Samsung has been using for several years and which is intended to faithfully convey the creators' vision. In SDR content, its implementation is not bad, although some imperfections can be noticed. The image is slightly dimmed, and the screen has a subtle pinkish hue resulting from an excess of red and blue in the white balance. Colour errors remained at a level of 3–4 ΔE units – and for the uninitiated: a value above 3 is the threshold where the average human eye starts to notice differences.

Much bigger problems arise in HDR content, however. Here, the white balance was not as much of an issue – a slight excess of blue did not significantly hinder things. The problem became brightness management. In practice, the TV "blows out" the image too much, causing details in the blacks to completely disappear. The final effect was far from what was expected, and the colour errors in this mode became quite significant. It’s hard to say why such a design decision was made, but it was clear that the factory HDR settings do not allow this TV to showcase its full potential.

We tested the LG G6 in the best factory mode for colour fidelity, which is FILMMAKER MODE. In the case of our test unit, this mode was reasonably well tuned straight out of the box. In SDR content, the only issue we noticed was the white balance, which leaned towards warmer tones. This made the image occasionally appear slightly yellowish, but overall, it wasn't a significant problem. The G6 performed a bit worse in HDR content. There, the white balance showed too much blue component. This caused the image to veer towards cooler shades, resulting in quite noticeable errors. As can be seen on our ColorChecker chart, the colours shifted towards these cooler registers. Nevertheless, considering the factory settings, the television presented a perfectly decent level. However, we know that OLED screens – particularly those from LG – respond exceptionally well to professional calibration, so we immediately proceeded to do just that.

After calibration, it was possible to make subtle adjustments to the white balance and significantly improve the image characteristics. In SDR content, the quality has become practically reference-level – most colour errors have dropped below a ΔE value of 1, which is the level at which the human eye can no longer perceive differences. This is a result that places the S95F among the absolute top TV models available on the market.

In HDR material, calibration also brought a significant improvement. The tendency of the TV to blow out the image was managed, as confirmed by the analysis of the EOTF curve. There is still a slight tendency to brighten the entire scene or occasional loss of detail in the blacks, but this does not significantly affect the overall perception. After calibration, the S95F shows its full potential and can be regarded as one of the best TVs on the market!

After completing a professional calibration, we gained complete control over the panel, and we managed to align all parameters to nearly zero. We were able to tune the white balance perfectly, which removed the factory's cool and warm tints from the screen. The effects are visibly clear in the ColorChecker test – the average colour reproduction errors dropped below the critical value of 1-2. And what does this mean? PERFECT colours, without any distortion! However, as a reviewer’s duty, we must point out how the LG G6 arbitrarily manipulates brightness, which is due to the EOTF curve's behavior. When we look at the standard synthetic graph, it might seem that the line is quite straight. However, the situation changes when we turn on the measurement filter, which shows how the television interprets brightness in actual, moving film scenes (EOTF in MOVIES). Then, it is clear as day that some of the smallest fragments on the screen are slightly overly brightened by the algorithm. Of course, for the average viewer, such a deviation will practically go unnoticed, but in the test of such an expensive screen, it’s worth noting – especially since we are talking about a model that has huge aspirations for the title of the best television of the year.

Samsung S95F offers a noise reduction feature that smooths tonal transitions. It works very effectively, but in practice, it can be too aggressive. Materials of lower quality – e.g. older recordings or videos from YouTube – become soft and plastic when it is enabled, resembling an image digitally smoothed in graphic software. Unfortunately, the natural film grain, which often adds authenticity to the image, disappears in the process. Fortunately, the television does not lose too much fine detail, e.g. in skin textures or environmental elements. Therefore, this feature is best used judiciously – depending on preferences, one can achieve a smooth but less natural image or one that is truer to the original. In our opinion, the most universal choice is the “Standard” setting.

Image scaling performs significantly better. The television handles lower resolution materials well – even 576p content looks quite decent, though slight blockiness can be observed. Overall, the effect is very good, although it slightly trails behind what Sony Bravia 8 (II) or LG G5 can achieve. It’s also worth mentioning a small imperfection of the S95F – in older materials, overscan may occur, causing a slight trimming of the left edge of the image.

No matter what one might say about the G6's issues with near-black signal, it must be fairly acknowledged that it handles heavily compressed material and lower resolution content extremely well. All unwanted, ugly tonal transitions are effectively reduced here by the "Smooth Gradation" feature. At the "Low" setting, the algorithm works flawlessly – effectively masking the artifacts resulting from strong compression without destroying the sharpness and details in the frame. Higher levels of this feature do further smooth the image, but they start to blur the real texture elements of the objects, so we recommend keeping this slider at a low level. As for the actual upscaling to 4K, the processor does an excellent job – edge sharpness and detail reconstruction are at the highest level, and in this respect, the G6 is on par with the global leaders.

The Samsung S95F excels in motion fluidity, presenting phenomenal performance. The panel operates at a native resolution of 4K with a refresh rate of up to 165 Hz, and when combined with QD-OLED organic technology, it delivers incredible results. Sports and games look sensational – the picture is fast, dynamic, and very natural. Additionally, the built-in motion smoother and blur reduction system allow you to customise the character of the image to your own preferences. You can opt for a more 'framey' effect with visible film texture or a smooth, cinematic spectacle. Every viewer will find a setting that suits them.

The LG G6 is an OLED television, so in the category of motion fluidity, it traditionally deserves the highest marks. The TV supports very high refresh rates of up to 165 Hz in 4K resolution, but most importantly – there are absolutely no signs of blurring on the screen. The response time of the matrix is virtually instant, ensuring that dynamic images remain perfectly sharp.

The same advantages of low motion blur and excellent motion fluidity characteristic of OLED panels are just the beginning, as the Samsung S95F has been designed with gamers in mind. The manufacturer has equipped it with four HDMI 2.1 ports – though limited to a bandwidth of 40 Gb/s, in practice, this has no impact on compatibility with consoles or PCs. We get a full package of gaming features: variable refresh rate (VRR), automatic game mode (ALLM), as well as a very well-implemented HGiG standard, ensuring that HDR titles look as the creators intended. This is complemented by Game Bar – a clear settings hub, where with one motion, we can preview and change all key image parameters. The proprietary motion smoother Game Motion Plus also deserves praise, as it can smooth out animation, which is especially useful in productions running at 60 frames, where stability is not always exemplary. While there is no support for Dolby Vision in games, it’s hard to consider this a serious drawback – Samsung compensates with other solutions. This is one of the best, if not the best, gaming TVs available on the market today.

The LG G6 is a true beast for gamers and one of the best-equipped TVs on the market in this regard. The manufacturer didn't compromise and equipped this model with four full HDMI 2.1 ports with a maximum bandwidth of 48 Gbps. This means that no matter which port you plug in your PlayStation 5, Xbox Series X, or powerful PC, you'll get the absolute maximum performance out of them.

The TV supports a full suite of gaming technologies: from VRR (Variable Refresh Rate), to AMD FreeSync Premium Pro, and Nvidia G-Sync Compatible. Let's add to that a remarkably low, almost imperceptible input lag and an excellently functioning game panel (Game Optimizer), which allows you to constantly monitor signal parameters. Gaming on this screen, with the perfect black of OLED and powerful refresh rates, is pure pleasure.
