After some more experimenting, I decided to change the gamma curve back to the old version, keeping the new RGB adjustment so the colors are still more correct and not yellow-ish. There were some scenes on Tatooine where the whites looked much more crushed than in others. That's what made me change my mind about it.

I also updated my color settings again, to make red colors less yellow, (made skintones look slightly more real) and I changed cyan back to the old setting. I made a new cyan setting to try and correct R2's hologram of Leia, the insanely blue lights on the tractor beam control in the death star, and some other things. The new setting resulted in other scenes looking weird like for example, Greedo's jacket looked oversaturated and dark.

I'll post the new settings and curve soon in post 3.
