make unity consider perceived brightness

[Bora M. ALPER]

Unity changes the physical brightness of the screen, which is weird, since human eye perception of brightness is different than the physical brightness of the object that is perceived. For clarification (and the reason), the first three paragraphs of this article might help: https://learnopengl.com/#!Advanced-Lighting/Gamma-Correction

Can we please make Unity consider perceived brightness while changing it?
