I think to confirm, I'd create an Applescript (or other small app) to  
ask the OS to return the display profile for both displays to be sure  
this works. It's possible that switching to mirror mode doesn't cause  
the display manager to update the 2nd display with the vcgt tag  
that's being used for the 1st display, but is in fact still using the  
1st display's profile, which might give the appearance thatchoosing  
mirroring after independently setting profiles unmirrored, works.
