I distinctly remember that I had some transcription of songs from the ...and Justice For All album that were in a special edition of some guitar magazine from the nineties, and they seemed to be really on point. Later I bought the full official transcription book, and boy was that a letdown. Completely different transcriptions that in parts didn't even make sense (IIRC, I haven't checked in a while).
The really sad thing is I cannot find that old magazine any more, at best it is somewhere in my parents house in the attic in an unmarked box, at worst it got lost while moving. But yeah, that was the first time young me realized these transcriptions were not, in fact, noted down by the musicians, but done by a 3rd party whose listening and guitar playing skill differed a lot from the actual musicians and writers. I approached all other sheet music with a very high degree of caution after that "incident".
I've seen interviews with musicians where they're asked a relatively simple question about the key a song is in or what's going on in a given riff from a music theory perspective, and the response is like "I don't even know what that means man I just play what comes to me". It's definitely not a given that a band would be able to transcribe their own songs, or tell that someone else did it correctly, even if they wanted to. Some people seem to just have an intuitive feel for playing music, which I envy.
There's rough rhythm-only cuts of Justice on music services (I think they were on the last reissue) and it's like listening to an entirely new dimension of those songs. I don't play guitar but my friend does and he was like "none of what we just heard was in that transcription book we had in high school." Heh.
Radiohead have a live piano version of Like Spinning Plates that you can recognise side-by-side but probably wouldn't be able to tell is the same otherwise.
