Research direction

Reproduce the behavior on mpv 0.33.0 on Windows 11 using async screenshot video and the reported icc-profile-auto settings. Compare screenshots opened in a color-managed viewer; done means screenshots taken with calibration enabled are not recalibrated or shown with the purple color shift.
