Your friend was probably buying modern pressings of stuff which are literally just a sympathetically mastered digital recording pressed onto a record, so yeah there was probably no appreciable difference.
I only buy old records for this reason: analog playback medium demands analog mastering. I have a Beatles album where side A is tube-mastered and that thing jumps out of the speakers like I'm waving a bag of sniff in its face: its night and day vs. listening on Spotify or whatever.
Moral of the story is not all vinyl is created equal. Saying that, one of the best sounding records I own is the 2015 remaster of Forever Changes - that was done from the original tapes though, and is very nice to listen to.
