Well I am switching to expanded now. I know its wrong, but its become clear xbox developers dont have a standard for these things. Alot of games seem to be made in pc level. Or 0IRE which is what it is in japan. Playing two capcom titles this week, res eve 5 demo, and street fighter, both had huge washout on my projector, which is calibrated to gamma of 2.2, and on the verge of nearly clipping blacks, so I know its not my set. Street fighter does not even have gamma adjust.
Even freinds who dont know anything about it came by and said "turn down that gamma" I have been forced to set it to expanded now, its not technically correct, but its clear thats how many developers make games at pc levels.
