Well, if it;s a minor advantage of say 0-5 to 1 where essentially you need a lot of accurate moves/engine lines to get the win eventually it's understandable.
Someone like Magnus wins today's games 10/10 times. Probably what differentiates him from the rest. +2 is an advantage where you can and should win with a couple of inaccuracies on the way too, so you dont need to be stockfish precise.
I get your point in general about engine lines and the viewers/commentators sounding more intelligent due to them, but today's game doesn't fall under that bracket IMO.
