I'm sure having traps in those small "wing" corners helps, but I can't tell how much. It might be that moving those traps to wall-ceiling corners would be a better use of their absorption. I'm not saying it would be! Just thinking out loud since you asked for comments. The only way to know for sure is to measure the room (ETF or similarly sophisticated) and see what changes without those two traps. If it gets measurably worse, then leave them. Otherwise you could move them because we know that wall-ceiling corners are viable. Especially those in the outer-most corners of the room.
