I've noticed that too. I've seen a couple of online videos that weren't that impressive. But, you can't judge by online videos. I'm sure the Mavic camera video is of the same quality as the P4, P4...
TOS is saying that it's just focusing errors by the users, that they didn't realize they have to set the proper "infinity" focusing setting, and that the same happened with the X5 at the beginning. Hope that's true!
