No. "assumed_gamma 1" uses the Display_Gamma value, which should be the 
gamma of whatever device you are going to display the image on, and 
defaults to 1.8 on Macs and 2.2 on PCs. The default (with no 
assumed_gamma specified) is to do no gamma correction at all. You could 
also set both assumed_gamma and Display_Gamma to 1, but that's more work 
than necessary.
