i believe Apple/Mac can show colorspaces and the way a certain image fits in that colorspace non compressed.
i have “softproofing” in Silkypix v10 pro but i can’t see the purpose in the way i see the changes but not if it’s in or out gamut.
i have a sRGB jpeg a AdobeRGB oocjpeg and a raw file
i see saturation changing so it shifts color in to the gamut of the printer or workspace.

Point is what for me would work is a graphic image colorspace resemblence which is overlayed a working space. (This way you can see how much is out of gamut in a model.
(i can’t find the post i think Sankos did explain it here
(i wanted to show those mac colorspace check as example. if you have a image’s colorgraphic as overley on this you can see where it sticks out the gamut of for example AdobeRGB. And see which colors are need to be compressed in order to fit.
this is easier to grasp then the “out of gamut blinkies colors”
