I’m telling you that even if those are the numbers on paper, the software and hardware are using tricks to achieve it which lower the overall quality.

So yes you get 4k pixels lit up on your display, but is it actually a better image?

And yes there may be high end hardware which can handle it, but the sw still made design choices for everyone else.

There are also image algorithms which are not as amenable to GPUs which are now impossible to compute effectively.
