In my experience, any time a bunch of people on the internet are sure that something is photo shopped, it's never photo shopped.
Quoting some randoms on reddit arguing about whether or not it was shopped isn't useful information, IMO. Randoms also think the moon landing is fake and 9/11 is a conspiracy by the American government.
People can go their entire lives without having an insightful thought or idea, and still think they are decoding secrets that no one else understands.
