Yes, there are a numbero fo utilities that will tell you the profile attached 
to an image, you may have an AppleScript to do this in Apple Extras>ColorSync 
Extras>AppleScript Files already...

Your description is incomplete, as you don't state the other RGB space 
involved. You need to watch out for issues such as what space you are in when 
doing conversions (forget profile to profile and change RGB space then reopen 
the saved file, being sure profile tagging is turned on) and whether the origi
nal file was ever gamut limited before, or is low gamut in nature. If its a 
clipped or low gamut file, you'll see no difference in moving to a larger 
space.
