Image can optionally have a tag as well. How are those colors actually mapped when going to screen? I believe that in the case of Core Graphics, everything is drawn into a sRGB device which is then mapped to the output device. So, a tagged imaged would go: Image profile -> sRGB -> monitor profile. Assuming that the output device is properly calibrated, you would get the same colors everywhere. Is this how it's supposed to work? Or is a tagged image supposed to go to the monitor profile directly?
