Mike Lavigne, who has invested in some good machines as well as a subscription to the Tape Project, seems to be unconvinced as to the superiority of, at least these tapes, if we are to accept his comments on Audio Asylum. Mike has a purpose built sound room as well as a Rockport record player and very high end gear.
As others have pointed out, the master tapes may have deteriorated in the decades since they were recorded, so no current reissue, in any hi-rez format, may be able to compare to the original LPs, or there may be other factors at play.
Attempting to answer these types of questions one dimensionally is usually fraught with problems.
