I see your point. I guess it also requires much larger screen. Because if 1 pixel man will be moving on my 27-inch fullhd screen, even though on 4k display it will be 4 pixels, it still be same physical size and not much easier to notice :)

It will be 4 pixels of different colors though, making it easier to distinguish the shape of the object.
