It's not the same. All of the Pokemon in Pokedex 3D are in the game already. You just have to view their icon with the camera to unlock them. The "DLC" just unlocks the monsters. I have no idea about Dead or Alive, might be the same thing.

Support for paid DLC was added recently, Nintendo's talked a lot about it. Tri G came out before that feature.
