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.
Unfortunately, when it comes to color reproduction right out of the box, the Filmmaker mode on the OLED910 performs poorly. The television overly emphasizes the color blue, and at times it almost looks like a store mode. It gives the impression that the manufacturer hasn't quite calibrated the device properly. The result is that colors look unnatural, and the overall effect resembles a somewhat exaggerated display from a market showcase. HDR content looks much better, where aside from a slight loss of detail in blacks, it's hard to find fault with anything. The problem is that in everyday viewing, it is the SDR materials that matter the most – and on the OLED910, they simply look bad and are far from what we would expect from a television of this class.
