Aha! This answers my puzzle! So, what you are saying is that it is a 
matter of (personal) choice: use the 'rgb' term in the POV-Ray code and 
all is well for most if not all cases, and if one wants (for whatever 
reason) to de-gamma the colors, use 'srgb' and adapt in consequence. 
Very well! This makes my life much simpler ;-)
