For this picture specifically, which is the one OP was talking about: https://images.squarespace-cdn.com/content/v1/50730c37e4b03a...

Yes, anyone could tell the difference between this taken on a dedicated camera and this taken on iPhone. Really, anyone. No matter the resolution.

It really does just look like a blurry mess. A cheap 150$ DSLR with a bottom-bargain Chinese or very old lens (at say, F1.4 or lower) would provide significantly better results.

I think that this was the image referenced with the "woman in a park" in the initial post https://images.squarespace-cdn.com/content/v1/50730c37e4b03a...

Oh, I read "woman in a parka" instead, and in combination with "blurry, smeared" I concluded that it was the image at night.

GP is the only person I can find in this thread referencing "woman in a park". Everyone else is talking about the "woman in a parka". I think you were correct in your assumption before. People are talking about the image without the dog.
