So an interesting thing about the whole kerfuffle with Spider-UK's art is the artist actually responded and basically it's "art direction is stricter with UB stuff and a lot of small changes had to be made". https://www.reddit.com/r/magicTCG/comments/1n6lxkd/spm_spideruk/nc6vthl/
The full-resolution image is a lot more clearly not-AI, you can even see the missing finger, it's just sort of lost in the low-res of the card image.
