Not sure I understand, the room doesn’t look angled to me.
But if that’s the TV location, don’t waste your time with a full system. You can’t get a good surround sound experience with a corner TV: You can’t get good separation from the speakers, especially with the seat at that distance, and the rear speaker locations you’d end up are all out of whack in relation to the fronts. Just stick with a sound bar and call it a day.
