I will always have to relearn Gamma handling each time I get a picture
this far along.
My personal preference are values that would help import/export with
people who work with pictures for a living.
I "think" Gamma handling is important, I just don't know the values.

(X) Really I don't worry about it too much. My monitor is also not
well calibrated. While I did a simple calibration procedure it is
probably useless since I adjust brightness depending on what feels
comfortable for the eye in current lighting conditions

Adding to that I also got the impression linear rgb is more
directly related to the physical characteristics of the material
(even if it is just a 3 element spectrum :D).

would you expect it to be just about as unintuitive under any other name?
