Samsung OLED S90D / S94D (WRGB OLED) vs Panasonic W95B

The Samsung S90D demonstrates impressive brightness performance in the tested film scenes, surpassing the 1000 nits mark in the first four shots—an outstanding result for an OLED display. In the final shot, which features a fullscreen flash of sunlight, the brightness dips to around 500 nits. While this is a decrease, it remains within a very good range, ensuring visibility and detail retention even in bright scenes.

Another key highlight of the Samsung S90D is its remarkable colour coverage, achieving 98% of the DCI-P3 colour space. This means the TV can reproduce an exceptionally wide range of colours, contributing to vivid and lifelike images that are particularly beneficial for films, high-quality video, and HDR content. The high colour accuracy and impressive brightness capabilities, makes the S90D an ideal choice for users seeking premium image quality across various lighting environments, whether in darker rooms or bright, sunlit spaces.

The Panasonic W95B is truly a bright screen, capable of achieving peak luminance levels of around 1400 nits. In brighter, well-lit movie scenes, this value translates into spectacular HDR effects that can leave a big impression. However, knowing our test setup, you probably see that in very demanding shots – such as the distant moon or helicopter lights in a scene from Sicario 2 – the TV does not impress. In such situations, brightness drops to around 200 nits, making the HDR effect much less visible. This happens because Panasonic prioritizes maintaining deep black levels without lighting up the background – for many users, this shouldn't be a cause for concern. However, it's important to remember that in these moments, the image starts to resemble SDR content. The coverage of the color palette also deserves praise, as it reaches about 93% of the DCI-P3 color space thanks to the use of the PFS filter (also known from QLED technology). As a result, most movies look very good in terms of saturation and colors, maintaining a cinematic quality of the image.

The S90D was tested in Filmmaker mode, which provides good colour reproduction, albeit with some imperfections that may be noticeable to more discerning users. This mode might appear overly warm, and those switching from Standard mode could find the change somewhat jarring. It is important to note that this issue stems from suboptimal settings, such as the white balance, rather than the Filmmaker mode.

In both SDR and HDR content, the device shows a drop in blue tones, resulting in colours appearing warmer than intended. In practice, this means that certain shades, such as sky blue or skin tones, may seem less natural, with a slight pink or yellow tint. The Colour Checker test confirms these deviations, indicating a shift towards warmer hues. In SDR content, the gamma chart reveals slight inconsistencies that make the image appear marginally darker, particularly in shadowed areas, which may obscure finer details in darker scenes.

In 4K HDR content, the EOTF curve exceeds the recommended level, leading to an overly bright display in some parts of the image, which can cause highlights to appear blown out. Overall, the Samsung S90D delivers a solid image straight out of the box, but for the best performance, further calibration is advised, especially with more demanding content.

In Filmmaker mode, the Panasonic W95B offers an image with quite accurate color reproduction, although it is not without minor imperfections. The white balance slightly leans towards red, which can cause a subtle warming of the image, and the gamma curve is slightly elevated, making the screen appear somewhat brightened. It’s good that the manufacturer has included this mode – even in its factory configuration, it provides a fairly natural look for movies. However, knowing how susceptible Panasonic televisions are to calibration, we decided to check how much the image could improve after professional tuning.

After calibration, the Samsung S90D in movie mode exceeds expectations. The white balance for HD and 4K HDR content has been refined to near perfection. While minor imperfections remain, they are so subtle that they don’t significantly impact the overall image quality. The colours are now more balanced, resulting in a natural reproduction of details, particularly in scenes requiring an accurate colour palette. It’s important to note that this model, in this size, uses a WOLED panel, which has a smaller wide colour gamut coverage and doesn't deliver the same vibrant colours as the 65-inch version with its QD-OLED panel.

The contrast has also seen notable improvements. Following calibration, the gamma curve now closely aligns with the expected line, achieving a better balance between the bright and dark areas of the image. The EOTF curve, which previously exhibited issues with overexposed scenes, now produces more accurate results, allowing for improved detail retention in the brighter parts of the image, especially in HDR content.

After professional calibration, the Panasonic W95B shows what it is really capable of. Color errors have mostly dropped below 2–3, making them practically invisible to the human eye. The excess red in the white balance has also been corrected, which has eliminated the slight pink tint, and details in dark areas no longer get lost due to overly strong dimming in the gamma. Improvements are also noticeable in HDR content – color saturation is now more stable and does not veer towards blue as clearly as before. It is truly a great television for watching movies and series in the highest possible quality. Although we know that Mini LED screens are not always perfectly suited for this, the W95B is an excellent example that with proper refinement, an OLED-like effect can be achieved.

The S90D TV handles tonal transitions exceptionally well. Thanks to advanced technology, the transitions between colours are smooth and natural. The noise reduction function can further enhance the smoothness of tonal shifts, which is particularly useful in certain situations. However, it's important to note that enabling noise reduction can also blur the natural film grain, diminishing the cinematic quality of the image. For this reason, it’s advisable to use this function with caution, as preserving the natural grain can enhance the character and authenticity of the content being watched.

As always, Samsung excels in image scaling from lower resolutions. The S90D effectively processes lower-resolution content, delivering a clear and accurate picture. The model’s outline is crisp, ensuring the image looks natural and detailed. Even the finer details, such as tree branches, are well-rendered without visible jagged edges that could degrade image quality. Thanks to its effective scaling, the S90D ensures that even lower-resolution content looks appealing, satisfying users who enjoy a wide range of content sources, such as regular broadcast or cable TV.

In terms of image processing, the Panasonic W95B performs excellently. The proprietary processor responsible for digital image processing effectively upscales lower-resolution content to 4K, preserving a great amount of detail and a natural appearance of contours. The final effect is impressive – the upscaling is at a truly high level, and Full HD content can look surprisingly good. The way the television smooths tonal transitions in low-quality materials is also worth noting. The algorithm does not operate as aggressively as in some competing models, but as a result, it does not cause loss of detail or blurring of film grain.

The Samsung S90D television features a 120 Hz panel, with the option to "overclock" to 144 Hz when connected to a compatible PC, offering exceptional motion smoothness. Samsung has long provided a range of image sharpness settings on a ten-point scale, allowing users to tailor the display to their preferences. In the UFO test, the OLED panel shows no signs of blurring, with pixel response instantaneous and effectively capturing dynamic movements. OLED technology is renowned for its performance in this regard, making it one of the best options on the market. The image remains incredibly sharp and detailed, even during fast-paced action, making the S90D an excellent choice for gamers and sports enthusiasts alike.

The 144 Hz panel used in the Panasonic W95B offers excellent smoothness, although in practice, considering how television content looks or the values to which next-generation consoles are limited, it's worth looking at its behavior when refreshing at 120 Hz. In this mode, the TV performs wonderfully – despite it being a VA panel, which is not known for the fastest pixel response times, motion blur here is minimal and difficult to detect with the naked eye.

The Samsung S90D is an ideal choice for gamers, featuring four HDMI 2.1 ports that support key gaming technologies such as Auto Low Latency Mode (ALLM), Variable Refresh Rate (VRR), and HDR Gaming Interest Group (HGIG). These features ensure smoother and more responsive gameplay, greatly enhancing performance during intense gaming sessions. The TV also includes a dedicated Game Bar, which makes managing game settings easy. This functionality allows users to quickly adjust parameters like the aspect ratio offering flexibility for different games and gameplay styles. Customising preferences is straightforward, further enhancing the convenience and enjoyment of gaming.

For PC users, the TV impresses by supporting a refresh rate of 144Hz when connected to a computer. Users with Nvidia or AMD graphics cards can also use G-Sync and FreeSync for a smoother gaming experience. However, it’s important to note that the TV does not support Dolby Vision, which may be a drawback for some. That said, Dolby Vision is not as widely adopted in gaming as in film, so this may not be a significant concern for most gamers. Overall, the S90D offers exceptional features for gamers, making it an excellent choice for those seeking outstanding image quality and modern technological solutions.

Aside from the previously mentioned drawback related to the VRR mode, in which local dimming does not work, the Panasonic W95B is a true gaming monster. The television offers practically everything gamers can expect – except for four HDMI 2.1 ports, as there are only two available. On board, we find an auto low latency mode (ALLM), properly implemented HDR modes for gamers, including HGiG, as well as support for Dolby Vision in games. This is complemented by an interestingly designed Game Bar, presented in the form of circles. While it may not be the most visually appealing, it serves its purpose – allowing a quick glance at key game parameters and adjusting settings without entering the system menu.
