> Does adding the 3D parallax not make it the Ken Burns effect anymore?
Yes.
Specifically, the Ken Burns effect describes taking a still, 2D image and panning and zooming on the 2D image in a motion picture.
Adding 3D parallax makes it something quite different in the eyes of many of us on this forum. It is cool! We would just not use the words "Ken Burns effect" to describe what you've made.
