Not completely - though I am basing this on adding my full iTunes library and not either resetting my iCloud Music Library or starting a fresh library and just adding all my albums. There seems a bit less mistake - primarily for me with live albums - but there are still quite a few of them.apple music messed up my library and I didn't renew my trial. Does anyone know if they have fixed Apple Music so it matches like iTunes Match does?
As my trial proves it doesn't even actually look at title. "Rebel Heart" and "Rebel Heart (Demo 4)" shouldn't be the same for AM, but they are, so even if you go through all your live recordings and add "Live at the S. S. L." to them, they will get "updated" to album versions anyway.

Just did a little check.
• create a library with one track called "Rebel Heart (demo 4)" 4:00, album tag "Iconic"
• enable iCloud, upload track, delete track, play track
• track is now the album version of song "Rebel Heart", 3:23, still tagged "demo 4" and "Iconic".
TL;DR: no.
