Those textures probably predate versions of POV-Ray with gamma 
correction. They were designed to look good on a screen with a gamma of 
2.2, so they are already "corrected" for that gamma, and applying the 
gamma correction just screws them up. This is why you can use other 
values for assumed_gamma: support of older scenes designed without gamma 
correction. The include file should probably be corrected or at least 
give a warning.
