In principle, depth and pop out are determined by the Blu-ray. Each 3D Blu-ray has a 1080p left and image, a 1080p right image, and the player's job is to output that to the TV as is. They can't adjust camera angles or reshoot the movie for more depth or pop out. Most likely, the differences you're seeing are from different Blu-rays, as they vary widely.
One exception is a 3D TV (or I assume a Blu-ray player) can zoom in and crop those left and right 1080p images to move the whole image forward or backward. I think many TVs call this "3D Viewpoint." Perhaps your Panasonic Blu-ray player has this function? If so, it might well give you a more pleasing image, but it's altering the director's vision and effectively pan and scanning the movie, if only a little. But again, most likely you're mistaking differences in movies for differences in Blu-ray players.
