DVDs 480p is better quality than YouTube’s 720p, and YouTube only gets ahead of DVDs after you switch to 1080p or above.
Modern online streaming at 4k usually doesn’t usually do any better than 20mbps (personal experience). Compressions helps, especially with av1, but for the most part, physical media is worlds better than streaming media is, because unlike physical media, the media companies have to pay for every mbps they deliver.
DVDs did ~10mbps at 480p using the mpeg2 codec. YouTube doesn’t recommend 10mbps until 1080p using x264 (mpeg2’s successor).
