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.
In Filmmaker mode, the Hisense E7Q / E79Q television was able to really surprise positively. Even after the first measurements, it turned out that the white balance is quite well calibrated, and the only minor deviation was a slight tendency toward a purple hue, which we mentioned earlier. However, this did not significantly affect the overall character of the image – it remained coherent and pleasant to perceive. A much larger problem turned out to be the brightness characteristics (gamma) in SDR content and the EOTF curve in HDR films. The television clearly brightened the image, flattening the contrast and taking away its depth. Gamma values could drop from the reference 2.4 down to about 1.9, making the image appear as if it were covered with a thin, milky layer. Fortunately, this is a problem that can be relatively easily corrected through calibration.
