The best factory mode in which we performed all our tests was "Filmmaker," which is quite standard in televisions from this manufacturer. However, let’s first examine its characteristics before the calibration process. The first aspect we will focus on is white balance, as it is critical to ensuring the image remains free from any colour cast. The chart clearly shows that in both SDR and HDR materials, two colours dominated significantly: red and green, resulting in a strong yellow tint that affected the entire image. This was particularly noticeable on the "ColourChecker" palette, where all colours shifted towards their warmer counterparts.
The second aspect we will assess is what we consider to be the two most important charts for evaluating picture quality: gamma and the Electro-Optical Transfer Function (EOTF) curve. Both aim to maintain appropriate brightness and contrast. The first chart, which describes the brightness levels in SDR materials, shows that the brightness was significantly lower than the reference value marked by the orange line. This resulted in a sharp increase in brightness and a notable decrease in contrast, which was inconsistent with typical OLED television behaviour. The EOTF curve, on the other hand, showed greater "moderation," subtly brightening the overall image only up to 50% of the maximum brightness.
We also took a close look at how Blaupunkt handles colors in movie mode, and here the situation is, to put it briefly, twofold. We must clearly separate what we see in the standard SDR format from what happens when HDR is turned on, as these are two completely different worlds. Let’s start with the better side of the coin. If you plan to watch classic television, YouTube, or older movies on this TV, you can count on really well-tuned colors. In our test sample, the white balance in movie mode was exceptionally accurate, which honestly surprised us. Of course, to not make it too rosy, we noticed some flaws. Looking at the gamma charts, we observed that the processor struggles with properly dimming the image in its brightest parts. Additionally, there is quite strong, at times too aggressive, red saturation, which resulted in noticeable errors in reproducing certain shades. Nevertheless, in general terms, 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 form. The excess blue in the white balance is so overwhelming that it literally clashes with the eyes, ruining any realism of the scene. Furthermore, the TV interprets brightness very loosely, which, when analyzing the EOTF curve, clearly showed that for most of the time the colors appear simply washed out and lacking depth. This is, by the way, perfectly visible in the color errors that become evident 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 feels forced and not properly refined.
