I'm on a Mac, running 10.4 Tiger.
I have yet to find out on how to examine the content of an install disc. Because just clicking the symbol will start the installation process. Maybe there are differences here between Windows and the Mac.
But, since I switched my color settings to "wide gamut RGB" (and leaving all the warning on, of course, for files that are not in the working space), PS accepts the files from DPP without giving me any warnings.
Which should, by sheer logic, mean that the color profiles are identical.
I would think that PS rather compares the profiles than their names.
