Especially when your browser or application requests a high quality bitrate, youtube compression is opus 128.
A person could make the argument that it’s not lossless so it’s not worth listening to, but opus is extremely high quality especially at that bitrate.
If you wanna try it for yourself, take a flac or whatever, upload it to yt, then use something like yt-dlp -x that defaults to the highest quality to redownload just the audio stream.

YouTube Music Premium offers AAC 256kbps as the highest quality.

Opus 128 is only for the audio of YouTube videos. Not YouTube Music.
and according to that same link it’s 160, not 128 (format id 251!). someone else pointed that out itt.
one of my downloads had an average bitrate of ~140 when queried with mediainfo, so i believe em.
I don’t have the premium account, what’s aac256 comparable to?
AAC 256 should be at least on par with MP3 320 CBR, might also be on par with ogg vorbis at the same bitrate
