I kinda understand how somebody who doesn't like opera could like those. It doesn't feel entirely opera-like. It constantly reminds you that it is a studio recording. Singing is generally very... intimate? Hushed perhaps. Singers occasionally will go into a quasi-whisper. The orchestra is indeed phenomenal but it is probably also the most closely miked in the recordings business. Music seems to come from a virtual vacuum and to be directly injected into your head without an intermediary. You can tell Currentzis isn't in the least interested in Così as theatrical piece in, he almost says so in the booklet — which is almost entirely dedicated to himself and how grateful we must be that he is saving Mozart from mediocrity.
But I maintain my recommendation for Annie: go for it! I will definitely buy Don Giovanni too when it's out because I'm that guy... We can exchange impressions then!
