An annotated test of MultiAngle output: what to zoom in on and verify.
Four front images on the top row and the back view generated for each below. The back is the side the photo never showed, so it is where invented detail shows up.
What to look at
Each back goes wrong in its own way: garbled lettering on the can and the chip bag, a mirrored title on the book, and the front artwork repeated on the box. Check any back against the real product.
