A white screen with high brightness can't be compared to white paper. If you have a bright lamp behind the white paper, you can begin to compare the problem. A white screen is fine for young people without any eye problems, when you get older and start having problems with the eyes, you might need to cut down on blue light to prolong the usage of your eyes depending on what problems you get. I have to use filters to remove blue light to not make my eyes worse.
That’s why I love redshift, I shove everything way over into the red and turn the gamma right down, I also killed the overhead lights in my office so it’s a comfortable quiet cave to work in.
