Get a blu ray (not even UHD) of Matrix (the 1999 one, there were never any sequels) and compare the lobby explosion scene with any torrent or stream.

Mind, it's not worth it for most movies. However, those flames are a good example of why bandwidth can matter.

But even a 20GB file? Streams are much more compressed, but I found files >20GB or so to be pretty much the same quality.

Which doesn't really matter though, you can also find 40GB files of most movies, they should (if encoded well) definitely match the quality.

It varies quite a bit, I see a lot of banding in various scenes on my TV with 20GB WEB-DLs compared to an actual 4K BR rip.

In most cases that is to be expected because WEB-DLs tend to be poorly encoded. You should be looking for a remux.

High quality torrents exist? I could download this right now: BD66 / m2ts / Blu-ray / 2160p / Scene / Dolby Atmos / Dolby Vision / HDR10. It's a 64GB file.

Yep, just search for "FraMeSToR" releases.

Yeah, at that point you're basically just downloading a bluray rip.
