Older Drivers (can't remember which version): Enabling HDR in Windows10, Google Chrome colors work fine.
Current Drivers (tested on 20.1.4 & 20.2.1): Enabling HDR in Windows10 makes Google Chrome's colors go off. https://prnt.sc/r3xxqv
Can try reinstalling older drivers 1 by 1, but each reinstall process is extremely slow and may take a long time until right driver works.
Try new adrenalin 20.9.2 driver. AMD informed that 20.9.2 driver fixes the issue of washed out hdr color in the driver release note.
