OK, I think I might understand better now. Is the result of the animation below the kind of mirror you want, to extend the image into the bleed area? I showed how it could be done in InDesign without going into Photoshop; I’m not sure if this is different from how you did it.
Using that method, below is what an exported PDF looks like on screen. Where the page edge meets the bleed appears to be seamless…
I wrote a script that I use for making a canvas wrap, which mirrors the edges. You can give it a try:

var useInch = true; //set false to use cm
var showUI = true; //set false to not have the user interface appear
