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.
We always test televisions in the best available factory mode – for the Samsung QN80F, this is the Filmmaker mode, and indeed, it offers the settings closest to the creators' intentions. However, this doesn't mean that everything looks perfect. In SDR content, the biggest issue turned out to be an unbalanced white balance – slight deficiencies in green and a noticeable excess of red led to noticeable color errors, and one could almost say there was a pinkish tint to the screen. This was clearly visible in the color checker test, where colors would "escape" their target fields – to the extent that a sensitive viewer's eye could catch it even without the help of a meter.
In HDR content, the white balance was much better, but another problem emerged – brightness management. The EOTF curve caused an overly bright image most of the time, which could affect the perception of contrast and made the screen slightly "flicker" during dynamic light changes. We have already discussed this in the paragraphs about black and HDR. Fortunately, Samsung leaves the user with plenty of options. The QN80F offers a rich set of calibration options, including a 20-point white balance – that's why we decided to check what this television is really capable of after proper calibration.
