Linear Color Space - Screencapture (Dark Screenshots)

Hi everybody!

I'm trying to make a very simple script to make a high resolution screenshot in the Editor (on Play). [Using Unity 2018.1.0b10]

This works fine in "gamma" color space, but using "linear" all screenshots get to dark. The script is just using ScreenCapture.CaptureScreenshot();attached to a standard Unity Camera, in a clean / empty Unity project, see the output below.



I have no clue what to do, or how to fix this. Any help in the right direction, would be highly appreciated!
