You answered the question in your first sentence. But if I elaborate - first of all, you don't know how efficient the beta testing was, only Paradox knows. Second, you can't prove that it's the most polished EU4 patch on release either, because your experience can differ from someone elses (also - recency and confirmation bias) and there's no mathematical or scientific way to measure how polished a patch is except to count bugs (which wouldn't really cover how "game-breaking" a bug is, just the number of bugs), and obviously a major update will have more room for error than a minor one.
That's only one point actually, you are saying that I can't proof 11.3 after beta being more polished than 1.14 on release. (Because if you took that for granted, that's quite good proof for efficient beta testing). Well, I can't. It's just my feeling and the feeling of a couple of people here.
But I would like to hear the opinion on this from paradox. Maybe they share your opinion or have data on it, that the 1.14 release was actually super-bug free and we are all just (recency-)biased. Then please tell us (Because I cant't believe that but am always open to proof) ! Otherwise, what's the problem with the beta-testing approach?
