What you see on the other side of A747 is actually superstructure, not part of A747's balcony. It houses a stairwell for crew and emergency use. The partitions between all the balconies are the same. You would have to stand on a chair to see over into your neighbors balcony.
You will lose a few degrees from your line of sight because of the superstructure extending out, but not enough to make it worth changing cabins. You are in a very good location right where you are.
