Samsung QD-OLED S90D / S94D vs Samsung Neo QLED QN95D

In the HDR effect quality category, Samsung S90D achieves remarkable results. On the luminance chart up to 10% window, the TV exceeds the magical threshold of 1000 nits, which is an impressive outcome. However, in the film scenes we tested, these values were slightly lower. Additionally, in the case of a scene with fullscreen sunlight glare, brightness drops to around 500 nits, but it still remains at a very good level. It is worth mentioning that this model stands out with very high colour gamut coverage, thanks to the QD-OLED panel used, which gives it an advantage over TVs with WOLED panels that cannot achieve such a wide spectrum of colours.

Samsung QN95D handles HDR exceptionally well, achieving peak brightness around 2000 nits. In tested movie scenes where the screen is fully illuminated, the TV delivers intense and realistic HDR content reproduction, significantly enhancing the quality of visual experiences. However, similar to the contrast, the dimming algorithm can sometimes exhibit limitations. Despite a significant number of Mini LED zones, the TV won’t amaze users with incredible lighting. For example, in scenes from "Life of Pi," where a bright moon appears against a dark background, and in segments of "Sicario 2," featuring intense lighting effects on a dark backdrop, the TV shows very poor performance. During such moments, the TV attempts to reduce the halo effect by dimming the image to a level reminiscent of SDR quality. This results in deep and uniform blacks, but at the cost of losing some details in bright areas. It’s a compromise aimed at maintaining the best possible black quality, although it does make the image lose some of its dynamism. Despite some flaws in the local dimming algorithm's performance, this TV deserves praise for its wide coverage of the DCI-P3 colour gamut. This is made possible by the use of a quantum dot coating, also known as QLED technology, which allows for vibrant and rich colours.

Samsung 65 S90D with a QD-OLED panel has been tested in Filmmaker mode, which the manufacturer has been using for years to provide the best possible picture settings. In this mode, the TV offers a fairly decent image but with some shortcomings worth noting. In terms of white balance in HD content, viewers may notice a dominance of the red color. This effect can lead to the impression that certain skin tones appear unnatural and the overall scene will be too warm, which in turn can affect immersion in the watched material. In scenes where subtle differences in color are crucial, these distortions can be particularly noticeable. Similar sensations may also occur in 4K HDR content. Changes in white balance in this case can be analogous, with a noticeably smaller deviation in red color. This can also cause certain details and colors to not be fully represented, making the image lose its naturalness.

When it comes to contrast, the gamma presents quite well, however, some errors are still noticeable. Gamma values are below the reference level of 2.4, which can result in bright areas of the image being washed out and dark areas lacking detail. This limitation can cause some scenes to lack depth and detail, which in turn affects the overall presentation quality. On the other hand, the EOTF curve related to contrast in 4K HDR content performs really well, showing that the TV can effectively convey differences in brightness. Nevertheless, it is worth noting that these values are slightly below the ideal level on the graph, indicating the need for further optimization in this regard.

Samsung S90D in Filmmaker mode offers solid color reproduction, but requires some adjustments to fully realise the potential of the TV, especially in the context of different types of content.

In the category of factory colour reproduction, the Samsung QN95D television has been tested in Filmmaker mode, which offers the best settings from the manufacturer. However, it is not entirely free of flaws. For HD content, there is a significant colour discrepancy, particularly in the white balance, where the red colour clearly dominates the graph. The situation improves with 4K HDR content, but there are still significant drops in blue colour reproduction. These effects can be observed in a scene from the film "Star Wars," where the main character is rendered in overly warm tones.

In terms of contrast, the gamma graph shows a large initial spike, indicating that the television effectively highlights the brighter parts of the image. However, at the end of the graph, we notice a significant drop, which may mean that details may be lost in darker tones. This shape of the gamma curve can affect how users perceive dark scenes, where some details may become too blurred or too dark, causing the image to lose clarity. It's also worth noting the curve corresponding to brightness (EOTF), which is quite correct, except for the initial drop.

Although the Samsung QN95D boasts impressive specifications and advanced technologies to earn the title of one of the best televisions on the market, it requires some improvements in colour reproduction and contrast to fully realise its potential.

After calibrating the TV, the Samsung S90D in film mode gains quality more than one might expect. The white balance for HD and 4K HDR content has been adjusted to near perfection. Although minor shortcomings can be noticed, they are subtle enough that they don’t significantly impact the overall picture quality. The colours have become more harmonised, aiding in the natural reproduction of details, particularly in scenes that require precise colour representation. It is worth noting that this model, in this size, uses a QD-OLED panel which offers broader colour gamut coverage compared to other sizes of this model that are equipped with a WOLED panel.

The contrast has also significantly improved. After calibration, the gamma graph is much closer to the expected line, providing a better balance between light and dark tones in the picture. The EOTF curve, which before calibration indicated issues with overexposed scenes, now shows significantly better results. This effect allows for the retention of more details in the bright areas of the image, especially in HDR materials.

After calibration, the picture on the Samsung QN95D television achieves truly impressive results. The white balance is perfectly balanced, and error readings rarely exceed a value of 2, which means that colours are displayed very accurately. Most samples from the Color Checker test fall within an acceptable error range, confirming that the television reproduces colours excellently. The contrast has also improved significantly, and the gamma curve is more stable, leading to better visibility of details in dark and bright scenes. However, it is worth noting the EOTF (Electro-Optical Transfer Function) curve, which shows some discrepancies in film tests. Although the television performs well in most scenes, in more extreme cases, details in black can still be lost - this is due to an aggressive dimming algorithm.

Nevertheless, these minor imperfections do not diminish the overall picture quality. After calibration, the Samsung QN95D delights with its visual quality, offering an exceptional experience that will certainly please anyone looking for a top-of-the-line television.

The television handles tonal transitions excellently, allowing colours to flow smoothly into each other, creating a natural image. The built-in noise reduction feature can further enhance these transitions, which can be useful in certain situations. However, it is worth remembering that activating this option may lead to excessive smoothing of the desired film grain structure, which in turn can affect the authenticity and atmosphere of the image. Therefore, caution is recommended when using this feature to avoid losing the character and depth of the content.

The Samsung S90D model effectively processes materials in lower resolutions. This can be seen in the displayed image. The model's silhouette is clear and naturally reproduced, with details well preserved. Additionally, the branches of the trees are well-defined, showing no visible jagged edges that could degrade the quality of the image. Thanks to effective upscaling, even lower resolution materials look attractive on the screen, which will surely please users enjoying a variety of content sources, such as standard cable or antenna television.

The Samsung QN95D television handles tonal transitions well, even in lower-quality materials, thanks to the noise reduction feature, which acts like a gentle gradient. This feature is incredibly effective, smoothly rendering the image and eliminating unwanted noise while significantly improving the quality of the displayed content. However, as is often the case, excessive effectiveness can lead to unintended side effects. In some materials, this feature can also blur elements that should remain sharp, such as film grain.

Despite this, the television performs well in terms of image scaling, eliminating larger jaggedness in the picture. In a scene where branches are visible, they are not overly artificially sharpened, which allows for a natural appearance, and the model does not have an artificial outline. Overall, this means that even in more challenging conditions, the film material presents itself satisfactorily on the Samsung QN95D. The only downside when watching HD/SD content (like regular terrestrial television) is that we have a slightly cropped image - this is caused by the so-called overscan, which cannot be turned off.
