The ones that make the annual rounds up here in New England are those foliage photos with saturation jacked. “Look at how amazing it was!” They’re easy to spot since doing that usually wildly blows out the blues in the photo unless you know enough to selectively pull those back.
If you want reality, go there in person and stop looking at photos. Viewing imagery is a fundamentally different type of experience.
We’ve had similar debates about art using miniatures and lens distortions versus photos since photography was invented — and digital editing fell on the lens trick and miniature side of the issue.
Portrait photography -- no, people don't look like that in real life with skin flaws edited out
Landscape photography -- no, the landscapes don't look like that 99% of the time, the photographer picks the 1% of the time when it looks surreal
Staged photography -- no, it didn't really happen
Street photography -- a lot of it is staged spontaneously
Product photography -- no, they don't look like that in normal lighting
A lot of armchair critics on the internet who only go out to their local park at high noon will say they look fake but they're not.
There are other elements I can spot realism where the armchair critic will call it a "bad photoshop". For example, a moon close to the horizon usually looks jagged and squashed due to atmospheric effects. That's the sign of a real moon. If it looks perfectly round and white at the horizon, I would call it a fake.
