Thanks for the lead. I installed it, finding a key for $7.50. unfortunately, the problems persisted. I'll stay on windows 10 iot Enterprise 21h2 for now.
This is a new computer that I built a few weeks ago. The main difference that I see now is going from a GeForce 1070 in my old one to a rtx 4070 in the new one. I also went from an Intel i5 to a ryzen. I'll see if there's major changes in the color/dithering etc between those video cards.
Using novideo srgb on both os's did give an improvement
