martin Martin, my feeling here is that we are sensitive to some kind of ... "flicker". Flicker is a term that could cover - strobing, pixel marching, pulsing, or any of a variety of other ills. If I take two screens, one which hurts and one which does not, there tend to be two kinds of differences. Either the one that hurts seems, when you look closely, to "flicker" (i.e. static images are subtly moving) or else it is painfully sharp. In that case, I suspect blue light but can't rule out a third, unknown factor.
What I can say is that we've come closer to hitting the nail on the head in some cases here. We now know - in the vaguest terms - what android phones are doing wrong, and it's color spaces. We know what Windows 10 is doing wrong, and it's image compositing. We don't know WHAT in that layer is going wrong, but we know what the problem is. We're getting there.
