Let me also remind you that all HDR modes (except for the fake HDR100) require a color coverage of at least 90% DCI-P3.
Most programs and even Windows system components expect not DCI-P3 (Rec.2020), but sRGB (Rec.709/SDR) as input. Therefore, Windows works exactly in the mode in which most software is made. And a lot of software doesn't even work with color management systems. Even some of the popular video players, that's what's amazing.
Moreover, as I wrote earlier, the color space management system in Windows was initially done incorrectly. Some display systems ignore the assigned color profile.
In theory, the color profile obtained after individual hardware calibration of the matrix should be loaded into the video driver and it should always convert the output video data arriving at the matrix in accordance with it. Regardless of the withdrawal method. If the driver is told to output sRGB by default, then the output of any program and OS components should automatically be converted from sRGB to real, native matrix space. If the software indicates that it decides how to output (via the API), then the driver passes this video data without conversion, as is.
Only AMD drivers have a built-in auto-calibrator for the EDID matrix in sRGB, automatically bringing colors back to normal, even on wide gamut panels. And they are trying to emulate (with loss of DD) sRGB on matrices with a smaller color space - 45-46% NTSC.
Therefore, owners of AMD cards and igpus have always been in PRIVILEGED mode for the last 17 years, compared to owners of Intel igpus and discrete Intel/NVidia chips.
In AMD drivers, just check the "Use Extended Display Identification Date (EDID)" checkbox and an automatic attempt will be made to auto-calibrate in sRGB any screen panel with more or less native space than sRGB. In new drivers starting with the Adrenaline version, this checkbox is clearly missing; instead, you need to disable manual color control in the screen settings - which (manual control) is always enabled by default in AMD drivers. The effect will be the same. 99% of buyers of AMD cards and video integrated devices do not know about this outstanding feature of AMD drivers, which elevates AMD cards head and shoulders above Intel/NVidia chips and drivers.
Any owner of an AMD card or igpu can see for themselves the radical improvement in sRGB color accuracy on their monitors and laptop panels. Those who own cheap IPS with 45-46% NTSC and who have wide gamut matrices especially benefit.
