Unfortunately there is no way to know either way other than listening to the end result
Assuming that no "digital mastering engineer" f*&*ed with it by the time it was released to the public

- Which is the point you are making above.
What's my point?
When an LP is cut with the involvement of " a good number of LP mastering engineers" that know this, the end product has a better chance of being "better" than whatever "a digital mastering engineer" mangeld up and relased as"Digital" .
The "debate" has never(?) been about the "medium" but the "ease" or "convenience" or "screwing around" with the original master before it's released.
This situation is analogous to what's been going on with software development over the years.
When you had to commit to producing a few thousand floppies for distribution, "someone" had to "do their best" the released software
a) will install b) won't break everything.
Fast forward to online updates....all bets are off. The "best effort" is still there....but the safety .net (!) is there , to release an update as soon as a flaw is discovered. No one has ever said software was better because it was
recorded on a floppy. It was better because it was
released on a floppy with all the logistical and $ nightmare it involved.
