I think iPhones do some pretty complex image processing, and other brands of phones go even farther. I believe there have been instances of phones adding in completely new details (although maybe I hallucinated that detail).

What’s the expected result and also what should we put as a “true” answer if we take a picture with our phones and upload it?

In the case of pictures taken with your phone, the "true" answer would be "real" as it's not a synthetically generated image, just some post-processing/cleaning-up. The overall classification is going to be affected by how much of the image has been altered, if it's only a small part, it shouldn't effect the overall outcome too much.

Samsung devices, for example, will add detail to what it thinks is the Moon.

> The test of Samsung’s phones conducted by Reddit user u/ibreakphotos was ingenious in its simplicity. They created an intentionally blurry photo of the Moon, displayed it on a computer screen, and then photographed this image using a Samsung S23 Ultra. As you can see below, the first image on the screen showed no detail at all, but the resulting picture showed a crisp and clear “photograph” of the Moon. The S23 Ultra added details that simply weren’t present before. There was no upscaling of blurry pixels and no retrieval of seemingly lost data. There was just a new Moon — a fake one.

I think the example of a person in the background's face was replaced with a leaf was from an iPhone trying to clean up the image and got confused.

Of course my favorite is the phone that recognized a humanoid shape and placed Ryan Gosling in the image.

If the iPhone one is the one I’m thinking of, it turns out the leaf was actually there.

Nah, Samsung was substituting in a really good picture of the moon for people's regular moon pictures: https://www.theverge.com/2023/3/13/23637401/samsung-fake-moo...
