1080 vs 4k | SDR vs HDR in 1 video (lemmy.ml)

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

Yes, which is exactly what I'm stating. Showing a forcibly non-upscaled video (or one where you've manually tweaked the upscaling for that matter) is likely not what you want because there are no circumstances where that is what you'd watch on that particular screen. It could perhaps work as an example of how that video would look if you had a 1080p monitor of the same size instead of the 4k one you have, since it scales in a linear fashion, a pixel of 1080p is 4 pixels in a square on a 4k screen. But that's likely not what you want to test. Instead the thing you do want to test is "does it matter if I download X content in 1080p or 4k? How big is the difference really?" And if that is the question you need to let it upscale.
