It does make a difference to me on a lot of my images and it's an effect I haven't read a paper about yet.
I've noticed that effect too, and it extends past still images.
If I capture something with my high-speed camera at 160x80 resolution and 60 000 fps and blow it up onto a 28" 4K display, it's practically impossible to determine what is in the image(even when moving!), but as soon as it's squeezed down into a tiny thumbnail size, it's much easier to understand.
Now to write a paper and get published in a scientific journal.
