Your method of comparison/evaluation strikes me as very good. Of course, you are correct...as you would be if your ears had heard it the other way.
My last investigation of vinyl was done differently. I went to a dealer and asked to hear the best he had available, price no object. ("Only" about $60,000). It wasn't much better than my old vinyl rig, and inferior to my digital in some respects, so I didn't upgrade.
I am a bit surprised that you didn't hear more difference, because LPs are usually mastered differently from digital discs, even if they start off with the same master recordings.
