TLDR: What (maybe) determined that the painting is a Raffaello is everything[1] BUT the AI/facial recognition, that just found very high similarities with a known painting of the artist, thus (possibly) confirming the attribution. BTW, it is not like copies were made only in Victorian era, it was fairly common during the Renaissance that contemporary copies were made, often by pupils of the painter. This obsession over AI related news seems not to fade. [0] Analysis of the colours used, renaissance art experts, etc.
