I have to point out that DVDs are in fact digitally compressed audio and video. The last mass market video media that wasn't compressed was VHS.
DVDs use MPEG-2 and AC3 for their compression algorithms (both lossy).
The algorithms that streaming services use for compression are leaps and bounds better than what DVDs can do. Further, there's been a lot of research dumped into optimizing perceptual quality at a given bitrate.
As a hobby, I've recompressed DVDs and blurays. With modern compression algorithms and codecs, for me a 1080p stream with AV1 compression and Opus codec is transparent at about 1500kbps. (Depending on the media, Cartoons can go much lower and live action might need more bits).
