Is there a video which compares 1080 and 4k and another one comparing HDR vs SDR?

When I watch 4k content I think, wow, this is great detail. But when I watch 1080 this is very good, but the tiny people in the background wouldn't be blurred in 4k.

And when I watch a dark SDR video I hate that the movie companies didn't release HDR quality although it's a recent movie/ series. But how would I know if it would be better?

I always think that the grass is greener on the other side, but how would I know?

Would it be hard to create such a video file? I guess with ffmpeg. But all else would need to be kept constant which is the difficult part

Not the 4 pixel problem. Sorry, I should've elaborated.

The problem that I actually want to compare how both, 4k and 1080 looks on that TV screen to answer the question: is 4k worth the extra space?

To answer that question, you have to take a 1080 and a 4k video and play both under real world conditions, i.e. the TV upscales the 1080 content to 4k.

Ah, I see. No problem. You'd have to switch back and forth in that case or have two of the exact same TVs to compare at the same time. (Some sets do a better or worse job of up-scaling). You'd also have to take into account viewing distance from the TV. At a certain distance it won't matter, but as you get closer, it matters more and more. There are view distance calculators available online to help with that.

On second thought, If you use the same source 1080p video and lock one in at 1920 x 1080 window and expand the other one to as full screen as possible. The full screen video will be up-scaled so you should be able to compare directly on one set.
