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 Philips OLED769 performs admirably in film scenes featuring small bright elements. With peak brightness reaching around 800 nits, the TV handles light sources like street lamps or stars with remarkable vividness and detail. However, its limitations become evident during scenes with full-screen brightness, such as sun glare, where brightness drops to approximately 250 nits. This is a common challenge for more affordable OLED models, which often struggle to sustain high brightness across the entire display.

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.

The "Film" mode on the Philips OLED769 proved to be the most faithful factory setting for preserving the source material, and it was the basis for our tests. However, like other factory presets, it has a few flaws. Let’s break down the key issues observed in SDR and HDR content.

In both formats, the white balance exhibited a noticeable dominance of green and red tones. This led to a yellowish tint across the image, resulting in yellowed whites and slightly unnatural skin tones. This was particularly evident in the "ColourChecker" palette, where colour samples leaned toward warmer shades.

In terms of contrast and brightness, two critical graphs tell the story: the Gamma curve for HD content and the EOTF curve for 4K HDR content. For SDR, the gamma value dips below the ideal 2.4 level, causing lighter parts of the image to appear overly bright. This overexposure reduces detail and depth in bright areas. In contrast, the EOTF curve for HDR content performed admirably, accurately maintaining details in both bright and dark regions. This ensures realistic, dynamic scene reproduction that enhances the overall viewing experience.

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 Philips OLED769 truly excels in colour accuracy. Any yellow tint previously seen in HD and 4K content is now eliminated. The Colour Checker test shows minimal deltaE errors, occasionally exceeding a value of 2, which indicates a nearly perfect representation of the director's intent.

When it comes to contrast, the results are equally impressive. For 4K materials, there was little room for improvement initially, but the gamma curve has been significantly refined. This leads to a more accurate rendering of dark and bright areas, resulting in a dynamic and realistic viewing experience.

Thanks to the calibration, the full potential of the television has been unlocked. The Philips OLED769 now delivers vibrant, natural, and high-quality images, making it an excellent choice for movie lovers and multimedia users.

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.

When it comes to lower-quality materials, the distortion reduction in the Philips OLED769 does well in smoothing tonal transitions, especially at the minimum setting. It's worth noting that film grain is not blurred, which is a positive surprise, as such negative phenomena often occur with other manufacturers. Overall, this is quite a decent solution. However, it should be pointed out that this setting does not work in HDR mode, where gradation issues are much more pronounced. In HDR mode, the TV struggles with smoothing tonal transitions and may exhibit more noticeable distortions and noise, reducing image quality in dynamic scenes.
