Seems a bit odd indeed. Here's some stuff that shows off 4k and hdr - and you test it on a screen without 4k and proper hdr? Well, no surprise you can't see any

Seems a bit odd indeed. Here's some stuff that shows off 4k and hdr - and you test it on a screen without 4k and proper hdr? Well, no surprise you can't see any effect from 4k and hdr? Granted the pixel reportedly has a good amoled screen - but I couldn't find any information on it handling hdr signals, beyond that it "boosts" the image (sounds much like the equivalent of audio compression/loudness for visuals). At any rate, since people have a hard time telling the difference between full HD and 4k in blind tests, I doubt that this could be anything beyond a subtle effect anyway? I have a 4k hdr TV here, so I'll have to try and see.
