DVD is limited to a 4GB size, bluray bumps that to 40/80GB which allows for virtually full quality media*.
Of course your local library might not have the film/show you want or the bluray is prohibitaly expensive or not even available in your region, in which case the arrrrrr stack of software can get you what you need automagically.

Only theaters (and people willing to drop several hundred dollars) get access to the 300GB+ uncompressed movie data DCP, so a 70GB 4K bluray rip (H.265 with Dolby Vision) is indistinguishable unless you put it on a theater sized projector and painstakingly look for differences in quality.
TV Shows however don’t get streamed in such high quality (and definitely not broadcast), so the bluray is the definitive top quality version of the media, and you can tell the difference in quality from a stream rip vs a bluray rip. The uncompressed version is a project file sitting on the studio’s server that you will never see or practically need (unless it gets shown in theater in which case the studio may opt to make a DCP).
I’m pretty sure there is some insane group out there that torrents DCPs but I’ve never seen them lol.
*8.5GB - dual layer is usually used for movies.
The biggest problem of DVD is the low resolution MPEG-2.
If it was something like AV1 (at 1080p), it would still be pretty competitive.
