Dembele was going for the ball and some of the angles show he probably got it. There was contact afterward, but it didn't seem that bad. I would not have given the 2nd yellow. From a Bayern fan perspective it is great to help secure the lead. From a neutral viewpoint it is a shame because this was great game with PSG resurging nicely in the 2nd half after a dominant first half from Bayern. From a PSG viewpoint it is devastating and probably feels unjust.
