This behavior is not consistent. First, it is confined to OSX only. Photoshop on Windows has no such weirdness. On OSX it seems to be hit-or-miss.
I think what I’m talking about is consistent on OSX. There are other things that aren’t consistent but let’s not get this issue mixed up with those!
Right you are. I was thinking about profiles randomly not appearing in other Photoshop dialogs. Photoshop on Windows happily lists all profiles with parentheses in the name. Photoshop's filtering of selected working space profiles from the print dialog is platform-independent. I see the same behavior on Windows as on Macs. Taking Andrew's experiment one step further, I deleted both the sRGB and Adobe RGB profiles from the common profiles folder. I then renamed Wide Gamut RGB to Adobe RGB and a random printer profile to sRGB. Neither showed up in the print dialog. It certainly appears that Adobe blacklisted certain working space profiles by name. I guess we're too stupid to handle the consequences. -Ethan
