As someone who occasionally downloads unlicensed content, I find that most movies (and occasionally high profile TV shows or those with a focus on visuals--like BBC's nature docs) are available in multiple qualities.
There are the basic 300-700mb copies for people who just want to watch something and don't have the time or bandwidth to bother with amazing quality (these look like your typical compressed cable or "tube" stream).
Then there are the 720/1080 versions which are still pretty compressed but at least encoded with decent settings and at a resolution that doesn't look bad on an average TV. Often these are "webrips" where someone capped the stream from Amazon or whatever online streaming rental service had the movie.
And last are the massive bluray rips that can go over 50GB in size and include 10bit HDR video, Dolby Atmos, etc. I never bother with these because honestly, if I'm pirating a movie/show it's because I'm not sure I'll enjoy it or it's just not available for me to watch yet. The movies I would want in maximum quality are the ones I would be buying anyway.
I'm sure plenty of people can't or won't buy the official blurays so these are the alternative, but for me, "bootleg" copies are the equivalent of "I'd watch it if it was on TV" but not a replacement for stuff I'm really invested in seeing at max quality because I love it.
Amazon's 1080p copies are usually very good quality, certainly comparable to the bluray release. Pirates have been able to download and strip DRM from there and itunes, etc. for a long time, no capturing+re-encoding necessary.
Depends on the content but if it’s something remotely popular, and was released on BluRay, the answer is yes.
The most popular torrent at the moment apparently 1.92GB BluRay rip of Joker (2019), with 8k seeders.
There’re 2 higher-quality versions found on the Internets, 6GB and 16GB. Both have 4k video encoded in 10-bit h265, have 5.1 / 7.1 audio, the former one has 1k seeders, the latter 100. These numbers are very approximate, I haven’t downloaded nor watched that movie. But usually, even 100 seeders is enough to saturate my 120 mbit/sec download link.
