VRayHDRI Colorspace Question

Is Gamma set to RGB the same as setting it to Inverse Gamme at 0.455
Seems to be. Didn't know if there was a benefit one way or another.

sRGB is a complex transform, which is only approximated by a gamma of 2.2 (or inverse of 0.4545).
It's however close enough to be nearly analogous: you'd be able to spot the differences if you flipped between images only in particular cases, and i'd wager never when the texture was inside the render, driving one or the other shader parameter.
