Every reliable assessment of image quality must start with selecting the most optimal, factory preset mode. In the case of the tested P7K/P79K model, the choice was made without hesitation for the "Film" mode. It is the mode that presents an image closest to the intentions of its creators, avoiding both the exaggerated brightness of the dynamic mode and the excessive dimming known from eco settings. And it must be admitted that, for a device in this price range, the factory calibration is surprisingly decent, although it is not without a few stumbles. The most noticeable shortcoming turned out to be the not entirely correctly set white balance. A slight dominance of the blue component gives the image a subtly cool, frosty character, straying from the ideal neutrality that the director intended to show us. The television handles the reproduction of greyscale in the standard dynamic range much better – the gamma curve is almost exemplary. The only slight reservation can be made for the darkest parts of the image, where a delicate deviation from the norm causes a loss of some detail in the shadows. The most significant challenge, however, for the TCL software was interpreting the HDR signal, as illustrated by the EOTF curve. The television follows its own, rather free path here – the darkest details are disproportionately brightened, followed by a noticeable slowdown in brightness increase for mid-tones. Fortunately, most of these imperfections are of a software nature, which can be eliminated. With that thought in mind, we proceeded to the process of professional calibration.
We also took a close look at how Blaupunkt handles colours in movie mode, and here the matter is, to put it simply, twofold. We must once again clearly separate what we see in the standard SDR format from what happens when HDR is switched on, as they are two completely different worlds. Let's start with the better side of the coin. If you're planning to watch traditional TV, YouTube, or older films on this television, you can count on really well-tuned colours. In our test sample, the white balance in movie mode performed exceptionally well, which honestly surprised us. Of course, to avoid being too rosy, we noticed some drawbacks. Looking at the gamma charts, we observed that the processor struggles with properly dimming the image in its brightest areas. Additionally, there is quite a strong, at times overly aggressive, red saturation, which resulted in visible errors in reproducing certain shades. Despite this, overall, the image in SDR is simply solid and watchable without a grimace on your face. Unfortunately, the magic fades when we re-enter the world of HDR. Here, Blaupunkt behaves as if we suddenly switched it to store mode, and in its worst rendition. The excess blue in the white balance is so significant that it’s glaring, ruining any realism in the scene. Furthermore, the television interprets brightness very loosely, which, upon analysing the EOTF curve, clearly showed that for most of the time, colours simply appear washed out and lacking depth. This is also perfectly evident in the colour errors that become apparent in this mode. Once again, we are left with the same conclusion: Blaupunkt in SDR mode looks significantly better and more natural than in HDR, which seems to be forcefully added without proper refinement.
