See the code comments for detailed explanation. But overall we use particular combinations of sRGB and gamma 2.2 encode/decode to match SDR applications while still ensuring HDR values are passed on linearly. This means the user interface and SDR content will display different in Windows HDR mode off and on, but that is consistent with other applications. Split use_hdr variable into use_hdr_buffer about the graphics buffer, and use_hdr_display about the chosen display in Blender.
