Your seat does look as if one leather panel is either not fitted with the same tension, or there is a fault in the hide.
Even with the way the seat is designed, your leather is not right, the inner panel is stetched way more than the outside one, from how I see it. More likely to be the leather than the base I'd imagine.
Certainly not the quality we'd expect from BMW. Dealer ought to be on your side, without question.
