Gamma/Tone Washing Out Image - How to Fix?

: some additional comments:

From the color grading page in the docs: “Note that bright colors become gradually brighter but much less than dark ones. Black remains black and there is a mostly linear part of the curve that is a bit steeper than the non tone-mapped curve would be. That results in some contrast enhancing.

There is a discrepancy in that the docs are indicating color grading should cause contrast enhancing but you’re saying it can cause contrast lost. Which statement is the true one?

The problem can’t be combatted with PP because that’s simply a hack retro-fix to the poor color rendition on the buffer. Additionally, changing lighting parameters will have no useful effect because the issue is on a flat plane in a heavily varied texture. The problem is relative color metric of the aerial image on a flat surface.
