I don't know. I remember it was introduced in 6.7.0 and quickly disabled in
later versions of 6.7.x, because of issues. In 6.7.0 I had a lot of issues with
HDR (HDR->HDR and HDR->SDR mapping), but SDR with ICC was working perfectly in
direct scanout. In 6.8.0 the SDR with ICC is also broken.

Do you see different colors and saturation in HDR when toggling direct scanout
on/off? I can see notable difference in some color tones, and no difference in
some other color tones.
