heyas; there is a simpler way to compare the two textures. first, size them the same (the ratio should be the same, since they use the same template). copy and paste one to the other using, say photoshop. turn the new layer to 'difference.' everything that is black is not different (zero difference). you will see weird colours where things don't match. this is straightforward, mathematical, and unbiased. just for your info.
