Sony Bravia 8 (XR80) vs Samsung OLED S90D / S94D (WRGB OLED)

Sony Bravia 8 performs reasonably well in terms of HDR brightness. A maximum brightness level of 880 nits is satisfactory and allows for well-rendered lighting effects in most scenes. In the tested segments of the films Life of Pi and Sicario 2, the TV presents itself quite well, offering vibrant and detailed images that fully capture the atmosphere of these productions.

However, a greater challenge arises in a scene from the film The Meg, where the screen is entirely very bright. In such situations, the limitations of OLED technology become apparent, as the TV loses brightness, dropping to around 450 nits. Such a drop is less satisfying, especially when the entire scene requires intense lighting. Despite these limitations, Sony Bravia 8 remains a competitive model, offering excellent coverage of the DCI-P3 colour gamut and 74% coverage of the BT.2020 standard. This results in rich colours and precise details, significantly enhancing the quality of HDR content viewing and making for a pleasurable experience.

In the tested film scenes, the Samsung S90D television achieves impressive brightness results, exceeding the 1000 nit barrier in the first four shots, which can be considered a remarkable outcome. In the case of the last shot, where a full-screen flash of sunlight is visible, the brightness drops to around 500 nit, but it still remains at a very good level. Additionally, the television impresses with a DCI-P3 colour space coverage value of 98%, which guarantees extraordinarily rich and realistic colour reproduction, further enhancing the image quality. This result makes the Samsung S90D an ideal choice for those expecting high-quality images in a variety of lighting conditions.

The best factory mode available on the Sony Bravia 8 television is IMAX Enhanced, which provides the most cinematic experience, although it is not set up perfectly. The TV tries to replicate cinema settings as faithfully as possible, however, certain shortcomings are noticeable. Starting with white balance, both for SDR materials and 4K, there is a clear dominance of blue. This makes the picture appear too cold, taking away its naturalness. Tests using Colour Checker show that colours shift towards cooler shades, which may lead to less accurate colour reproduction and makes the image less realistic.

As for brightness and contrast characteristics, gamma shows a significant drop at the end of the graph. This means that dark details may be too dim, while bright elements are too bright, causing them to lose subtlety and become less visible. As can be seen in the sky - in the comparison photo. Meanwhile, the EOTF curve is significantly above the reference value, causing the bright elements of the image to be too intense. As a result, users may perceive the image as unnatural, and bright areas may lose detail, negatively impacting the overall viewing quality.

The S90D television has been tested in Filmmaker mode, which offers good colour reproduction, although with some imperfections that may be noticeable to more discerning users. This mode may seem too warm, and users who have switched from Standard mode might experience a slight shock. It’s worth noting that this state of affairs is caused by poor settings, such as in the white balance, rather than the Filmmaker mode itself. In both SDR and HDR content, the device shows drops in blue, causing colours to appear warmer than they should. In practice, this means that certain shades, such as sky blue or skin tones, may appear less natural and more tinged with pink or yellow. The Colour Checker test confirms these deviations, showing shifts towards warmer tones. In SDR content, the gamma chart indicates slight fluctuations, which may result in the image being minimally darker, especially in the shadows. This can affect the clarity of details in darker scenes. Meanwhile, in 4K HDR materials, the EOTF curve is located above the recommended line, leading to some parts of the image being displayed too brightly, which can cause clipping in the brightest areas. Overall, Samsung S90D delivers a solid picture straight out of the box, but for the best results, especially with more demanding content, additional calibration is recommended.

The calibration process of the Sony Bravia 8 television has brought significant improvements in image quality. The white balance has been distinctly enhanced, both for SDR content and 4K HDR, with minimal errors in the middle section of the graph. Gamma proved to be one of the biggest beneficiaries of the calibration – it has been completely stripped of previous drops, which significantly affected brightness stability and better detail reproduction in dark parts of the image. The EOTF curve has also been levelled out, making bright elements of the image appear more natural, and the overall tonal dynamics are now more balanced.

However, the most attention should be paid to colour reproduction, where despite the calibration, there are still some issues. Sony has omitted the use of a CMS system in this model, which allows for very precise control over colours. Consequently, the Colour Checker test for 4K materials still shows significant errors in colour samples. Despite these difficulties, we recommend carrying out the calibration, as the effects are noticeable and significantly enhance image quality, especially in terms of brightness and contrast.

After calibration, the Samsung S90D TV in movie mode looks even better than one might expect. The white balance for both HD and 4K HDR content has been improved almost to perfection. Although minor errors can still be noticed, they are so minimal that they do not significantly affect the picture quality. Colours are more balanced, leading to a natural reproduction of details, especially in scenes that require a precise colour palette. It is worth noting that this model in this size is equipped with a WOLED panel, which has less coverage of a wide colour gamut and does not offer as rich colours as, for example, the 65-inch version, which is equipped with a QD-OLED panel.

The contrast has also seen a significant improvement. The gamma graph after calibration is much closer to the expected line, providing a better balance between bright and dark areas of the image. The EOTF curve, which showed problems with overexposed scenes before calibration, now demonstrates better results. This effect allows for greater detail to be preserved in the bright parts of the image, especially in HDR materials.

The fluidity of tonal transitions in low-quality materials on the ChooseTV 8 is lacking. Unfortunately, the gentle gradation feature (which was available in previous models) is missing, which is a significant downside. The digital noise reduction function can improve tonal transitions quite well, but it also tends to remove some details, such as clouds in scenes from the film The Martian, which may not appeal to everyone. When it comes to digital processing, the Sony XR80 TV performs quite well. The model in the test scenes is displayed without noticeable errors, and the branches in the background are not overly jagged. This shows that ChooseTV 8 is capable of processing complex image details at low resolution well.

Television S90D handles tonal transitions very well. Thanks to the technology used, transitions between colours are smoother and more natural. You can also use the noise reduction feature, which further smooths out tonal transitions, which can be useful in certain situations. However, it's worth remembering that turning on noise reduction can also lead to the smoothing out of desirable film grain, thereby reducing the cinematic feel of the image. For this reason, caution is advised when using this feature, as it’s better to leave the natural grain that adds character and authenticity to the content being viewed.

Samsung, as always, does not disappoint and excels in scaling images from lower resolutions. The S90D Samsung TV effectively processes lower resolutions, as seen in the visible image. The outline of the model is clear and accurate and, as a result, looks natural and detailed. Moreover, the branches of the trees are well-represented, showing no significant jaggedness that could degrade image quality. With effective scaling, even materials in lower resolution present attractively on the screen, satisfying users who prefer various sources of content such as regular antenna/cable television.

Sony Bravia 8 offers a maximum refresh rate of 120 Hz, which lays the groundwork for smooth viewing of dynamic content such as sports and games. As a result, movements are sharp and fluid. For more demanding users, the Sony XR80 television is equipped with an advanced motion smoothing system, which is divided into three segments: Smoothness (Film), Smoothness (Camera), and Clarity. The first two are responsible for adjusting the level of blur and smoothing of the image. The third option, concerning clarity, will be described in more detail below. Each of the parameters can be tailored to personal preferences, allowing users to find the optimal setting suited to their individual needs.

Samsung S90D TV is equipped with a 120 Hz panel, with the ability to overclock to 144 Hz with the right PC configuration, providing exceptional motion smoothness. For years, Samsung has offered a variety of ten-point settings for image clarity, allowing users to adjust the display to their preferences. In the UFO test, thanks to the use of an OLED panel, there is no sign of any motion blur. The pixel response is instantaneous and perfectly captures dynamic movements. In this aspect, OLED technology is considered one of the best on the market. The image is incredibly sharp and detailed, even during fast action, making the S90D an ideal choice for gamers and sports enthusiasts.

Sony Bravia 8 has significantly improved its compatibility with consoles compared to earlier models. The TV supports variable refresh rate (VRR), which eliminates screen tearing, and is compatible with graphics cards, ensuring smooth visuals. The auto low latency mode (ALLM) reduces input lag, which is crucial in fast-paced games. Dolby Vision with low latency additionally provides impressive HDR effects that look fantastic during gameplay.

The Sony XR80 TV also features a Game Bar, which allows quick access to settings and monitoring parameters while gaming. An interesting option is the ability to enable a virtual crosshair on the screen, which can provide a slight advantage in shooter games.

A downside is the lack of support for 1440p@120hz resolution, which could make gaming easier for users with less powerful graphics cards. Additionally, the Sony XR80 only has two HDMI 2.1 ports, one of which is typically used to connect an audio system via eARC, limiting the number of available ports for connecting next-gen consoles.

The Samsung S90D television is perfectly adapted to the needs of gamers, offering four HDMI 2.1 ports that support key features such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). With these technologies, gamers can enjoy smoother and more responsive gameplay, significantly enhancing comfort and performance during intense gaming sessions. An additional advantage of the television is the special Game Bar, which allows for easy management of game settings. This functionality enables quick adjustments of parameters, such as changing the aspect ratio of the television screen, which can be useful in various games and types of gameplay. Users can easily customise their preferences, making the use of the television while gaming even more convenient and enjoyable. As for PC users, the television pleasantly surprises. When connecting a computer, the panel is able to achieve a refresh rate of 144Hz, and users of Nvidia or AMD graphics cards can enjoy features such as G-Sync and FreeSync. However, it should be noted that the television does not support Dolby Vision, which may be a downside – although it is worth considering that Dolby Vision is not as popular in the context of games as it is in films. Nevertheless, the S90D television still offers excellent features for gamers, making it a great choice for gaming enthusiasts looking for outstanding picture quality and modern technological solutions.
