So clearly my display profile is introducing some clipping in the colorspace conversion. Its a shaper matrix profile. Maybe I should just try a matrix profile…
Nevertheless I think the indicators show the blown areas in the lights and also the out of gamut stuff fairly well for this image.
For color you can get a pretty good idea from the vectorscope as well… linear rec2020 histogram profile with a couple of flagged areas selected.
