I have had similar experiences when comparing different mastering. I have a top end LP 12 and similarly chosen digital end that is voiced similarly and have done extensive comparisons between the same performance and mastering in vinyl, stored files, cd and streaming and found them to sound the same... with the caveat that vinyl has a fairly large variation based on the pressing number.
So a similar but not the same conclusion is that high variation in sound quality comes from the performance, mastering, and components you choose... but there is no unique or significant advantage in the medium... well, other than no pops and surface noise in digital.
