What about choosing resolution and graphics fidelity before downloading?

"4K textures" aren't textures for 4K screens. It's just a size of 4096x4096.

There are instances where those texture numbers will correlate with the screen like UI elements.
But in general, that's not true. If you zoom in on an object, you might only see 1/8th of it, so you're only seeing 1024x2048.
The idea of '4K assets' is largely a misnomer.

Many games don't have different sets of assets for the resolution. Xbox Series games might in some cases, but it's not the norm. Other consoles don't do that, and PC tends to have texture quality as a separate setting from resolution, because they don't have to correlate.

Exactly, but you can't get that into people's head. 

I remember when Rage came out with with it's 32k textures and people went: "Game has low res textures. It looks so bad when I get close to it". That wasn't the point of implementing it. It was to have unique textures across the surfaces and they did a great job with it. The places you visit have all a unique look to them.
