Ah, yes, we have a problem here:

With POV-Ray 3.7, only the assumed_gamma values of 1.0 or 2.2 work as 
previously, even when a #version 3.6 statement is present.


Try using "assumed_gamma 1.0" in the scene, and setting the 
"Display_Gamma" and "File_Gamma" INI file options to 1.8333 (=2.2/1.2); 
I'm not perfectly sure, but I /think/ this might do the trick. Make sure 
to /not/ use PNG, HDR or EXR as output file format though, as those are 
too smart file formats and won't be fooled by this kind of hack.

HDR images are "gamma-safe", you can't do anything wrong there.
