I'm not who that was directed to, but I used a file compare program (Beyond Compare) to compare the same image from two sources; a direct download from Pottermore and from my linked B&N account. The middle image is the difference. I don't know how the diff is calculated, but it definitely shows something there. I edited the pattern a bit out of paranoia, but that's a good representation.
