Other comments have pointed out valid things about cameras and resolving power. However there’s one phenomenon that might explain this feeling, and it’s the fact that not all 4K is created equal.
For an example of this, look up videos comparing the 8K video out of smartphones versus 4K video out of a Cinema camera like a red or arri. The Cinema cameras produce a very detail rich image, but the 8k phone video looks overshaprened because it’s not actually capturing more detail, just more pictures. The lens and the sensor in the phones is not capable of resolving 8k.
Phone manufacturers try to compensate for this by applying a sharpness filter, which does not create detail but simply adds boldness around detail that is already there. That sharpness filter is one of the things that make smartphone video look like it was shot on a phone despite the high resolution.
One of the things you might be seeing in “super detailed 4k” is overshaprening applied onto a video clip that has a ton of detail. When you do that it creates this weird crispy feeling to footage that is immediately impressive, but not enduringly beautiful. If you go into a electronic store and looks at TVs, all of them have the built-in sharpness filter turned up to try to wow people on the first glance. This might be the phenomenon you’re seeing.
However there’s a reason why filmmakers don’t oversharpen everything, it’s fatiguing. It looks fake, it looks wrong.
