I flew EK last week. The A380 had cameras looking forward and directly down from around the nose, as well as a camera mounted high on the tail, giving a great overview of the plane and the forward view.
The 777-300ER has just the forward and downward looking cameras.
Here's a video someone took of the tail camera view, on the IFE, during landing -
