I'm colorblind, so what has gotten worse for me are some types of action computer games. Before when my Sprite was running through fields, shooting nazis, I could spot the ones in camouflage by looking for small pixelation differences. But now the graphics have gotten so good that it is actually color hints that give them away. There used to be color hints back then, but of course I didn't use them. So now I run into hard limits on these games, where they become memorization exercises rather than observation exercises.
As an aside, my optimism on when therapies for treating color blindness would be available was higher in the past as well
