You're not wrong. 

There are two reasons why I sometimes wonder why there is no 
"Gamma_correction yes/no" instead of assumed_gamma;

- assumed_gamma seems to generate a lot of confusion although the way it 
works is technically correct.

- Working with POV-Ray is like working in a photo studio (even for outdoor 
scenes) where you have full control over the lighting scheme and thus over  
contrast range / distribution ('gamma').
