Gamma amdgpu vs amdgpu-dc

I don't know how to capture the screen with gamma so I did a capture with
imagemagick and applied gamma with gimp so the issues are visible.

I've also took a picture (attached). On the left is amdgpu-dc on the right
amdgpu, gamma 3 (xgamma -gamma 3), kernel 4.17. See the trees and the grass on
the left. Why do they look different on the same gamma values?

As I said, this happened before and I've fixed the issue with gimp by changing
images brightness and hue/saturation, but now with amdgpu-dc from 4.17 the
issues are back.
