Regardless of the actual effect on sleep, the "night light" modes for screens very much reduces the eye strain I feel. So much so that I've enabled some version of it on every screen I use, permanently, not only at night.
I find it much more pleasant and comfortable. Interestingly, I've gotten so use to it my brain compensates for the color change and it looks pretty normal to me.
