Subject: Bug 1915082 - From ScreenCapturerSck request frames in sRGB
 colorspace. r=webrtc-reviewers,ng

The desktop capture path has no colorspace handling for RGB, and libyuv assumes
sRGB by default. ScreenCaptureKit returns frames in the display's colorspace
unless told otherwise. On modern macs this is 'Display P3' and will render
inaccurately when interpreted as sRGB.
