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.
While testing the Panasonic W85B, we of course started with the Filmmaker mode, as it is the gold standard today for watching content "as the director intended." The problem is that this TV is quite far from those intentions. The biggest issue turned out to be an excess of red – in both SDR and HDR. The picture often looked overly warm, and in some scenes, it appeared almost "blazing." Additionally, there’s the issue of brightness management. When we looked at the gamma and EOTF charts, it was clear as day that in most scenes, the TV brightens the image more than it should. The effect was easy to predict. Details can get lost, leading to flattening and clipping across the entire screen. Of course, we know how to improve this, but it must be said honestly that it requires quite a bit of work in calibration. Out of the box, the W85B does not provide a reference-level picture – it is rather a TV that will always interpret colors and brightness a bit "its own way" without professional adjustments. Unfortunately, this is to the detriment of the viewer.
