"Near perfect copy of the original master recording"
If you only realized how useless that can be! Take (for an example) original recordings which were then mastered for release by Bob Ludwig,, THOSE LPs are worth multiples of what other Lps are worth, Because he CHANGED the Master to sound better..
Also some new releases 'true to the original master' Sound like garbage, since ALL original tapes ware ALWAYS adjusted when being made ready for pressing.. And not left as is.
True having an actual master to START WITH is nice, ... But they are only starting points.
