For the record, the saucer section deck numbering goes from Deck 1 (e.g. the Bridge at the very top of the ship) down to deck 18 at the bottom, so we'd expect the see any rooms on Decks 1-10 with windows sloping forward and any rooms on decks 11-18 with windows sloping in different directions, primarily backwards.
We see a bunch of ship's quarters from Deck 8 and Deck 9 in the show. All of them have the windows sloping forward from the top rather than upside down, which is as it should be.

That being said, we also see some rooms on decks 11-18 and their windows also slope forward. No in-universe explanation for this is given. In reality, of course, the reason is that these are simply the usual "quarters" set being repeatedly redressed.
