The calibration process turned out to be spot on, especially in the context of standard dynamic range (SDR) content. We successfully managed to eliminate the tendency of the television to showcase cool tones, restoring white to its natural neutrality. Moreover, the precise adjustment allowed us to correct a slight error in the gamma curve, enabling the darkest parts of the image to regain proper depth, without any signs of unnatural brightness. The results are measurable and impressive – in the ColorChecker test, the vast majority of colour reproduction errors fell below the perceptual threshold, achieving a deltaE value of below 2. This is a result that more expensive models would not be ashamed of. Unfortunately, in the case of HDR content, we encounter a wall in the form of the panel's structural limitations. And although we managed to bring the colours into line, the software's specifics mean that the television still adapts brightness in its own way, as evidenced by the persistent, non-standard EOTF curve. To summarise, calibration adds tremendous value, but it is important to be aware that it won't overcome certain physical barriers. The slightly elevated blacks, resulting from the lack of local dimming, and limited peak brightness mean that HDR content won't always be able to showcase its full potential. This is simply not the main task of this display; its true strength, especially after professional tuning, lies in viewing SDR material.
The calibration process left us with extremely mixed feelings. On one hand, we noted considerable success in the area of colour. By using the options available in the menu, we managed to tame the white balance and bring it down to an acceptable level. As a result, SDR content finally freed itself from the irritating red dominance, and the HDR image stopped resembling the vivid, retail demonstration mode. The entire colour palette and its saturation were also clearly corrected – maybe not perfectly, but to the extent that the software allowed, and the difference was visible to the naked eye.
And on this, unfortunately, our list of corrections pretty much ends, as M95E simply didn't allow for any more. As we signalled earlier, most settings related to the brightness of the image do not respond to our commands at all. This means that we were not able to control its fundamental characteristics in any way – neither the gamma curve nor the EOTF. In practice, the television still tends to darken details in SDR content, which was confirmed by the inflated gamma, merging details in the shadows. Meanwhile, the EOTF curve in HDR mode still mercilessly exposed all those previously mentioned problems with chaotic local dimming management. And although the calibration process itself achieved a lot, removing most of the colour issues, in the end, we had to capitulate.
