Upscaling sometimes resamples images. It's just just a "closest neighbour and then some" duplicating, you have directional gradients, multidirectional gradients, all sortsa bullshit.
I notice the 4k difference in blueray movies but not much in games. But the HDR is noticeable in games. I'm on a 4k 120hz Tv and Series X. I imagine games will get better tho.
My wifey gone for a week visiting her fam, she asked me if I wanted someone to come stay w me while she gone, I responded, yea your sister. Lol. She didn't find it funny.
