Playstation games over the years have used X for confirm in many (western) regions. I’m not sure the origin of this but it was always that way growing up.
Circle was used in Japan. Localisations like Final Fantasy using circle were the exceptions to the rule (I guess it was too hard to change it?)
X being confirm for everybody is a relatively recent thing
It's not that these images are perfect - it's that they're close enough.
The "problem" is that these images look amazing with a minimal touchup - something which would happen anyway to a real photo.
An extra hour to two fixing some AI artifacts (the ol' droop-eye and derp-hand) is a LOT cheaper than getting actual people out to an actual location and taking an actual photo.
EDIT: I just realised the tent is on fire 🤡
