During testing, the Philips PML9009 performed best in the factory "Filmmaker" mode, which we evaluated across both SDR and HDR content. A key characteristic observed in this mode is the EOTF curve’s behaviour in HDR content and gamma settings in SDR, designed to enhance image accuracy. However, the PML9009 presented noticeable issues, particularly with white balance, as a pronounced red dominance created a yellow tint across the entire image. This affected skin tones and white areas, with faces and whites appearing unnaturally warm. The colour shift was confirmed through the "ColourChecker" palette, where colours leaned towards warmer shades.
In the gamma analysis, responsible for image contrast, we noticed considerable inaccuracies early on. Our measured values spiked above the reference, causing dark scenes to lose detail and merge visually up to about 10% screen brightness. Following this, the values dropped below the target line, further degrading contrast—an area already challenging for this model.
In HDR content, the white balance remained similarly flawed, and the EOTF curve also restricted brightness levels, resulting in a dim, muted image. Colour inaccuracies were even more pronounced here, with lower luminance levels causing large deviations from accurate colours, which were clearly visible on the error graph, often exceeding acceptable limits. While aiming for cinematic quality, this mode ultimately fell short in delivering balanced colour and contrast fidelity.
The best mode in Sony televisions is the IMAX Enhanced mode. Although IMAX is mainly associated with the cinematic experience, here the color reproduction right out of the box is average. In the case of lower quality materials, such as HD – regular TV or YouTube – it is worth paying attention to the white balance. It is characterized by a deficit in red and an excessive dominance of blue, which gives the image a pinkish hue. The brightness characteristic, or gamma, for HD content is quite decent, but a slight boost may cause the image to become washed out and appear as if it is behind a light fog.
In 4K HDR content, the situation looks a bit different. The white balance shows a significant boost in blue, which makes the image appear unnaturally sharp and gives it an artificial feel. Such an exaggeration in color reproduction may not appeal to everyone, especially if one prefers more realistic shades. Additionally, the EOTF curve in Sony X90L looks quite decent at first glance. However, at the end of the graph, there are certain fluctuations that suggest the television is trying to maintain the appropriate brightness to avoid overexposing larger elements.
