Calibration results

In addition to the calibration results, I would like to share with you all the nuances that amateurs colorists may face. First of all, I chose comfortable brightness for eyes during the daytime (in my case the brightness value was 30%, 250 cd/m²). Secondly, I switched to User mode and disabled (if enabled) Shadow Boost, Dynamic Dimming and ASCR technologies. These are the technologies that are responsible for automatic adjustment of backlighting and compensation for lack of brightness on relatively dark gradients (shadows). The last thing I did was to equalize manually the color temperature of the screen with the help of RGB channels and actually started the calibration process in DisplayCAL.

The Blue Channel is the only parameter I had to adjust to achieve a normal white temperature of 6500K. The Red and Green Channel remained unchanged. After two hours of the calibration, I was able to "squeeze" the following results off the monitor:

In this form, the monitor is ideal for working with graphics, it surpassed most of the declared factory values, in particular, the result of DCI-P3 was great, the contrast and the minimum deviation of ΔE*94.
