I'm guessing what the parent might have wanted is something straight out of the Camera app (or Halide), without any further post-processing.

It could be helpful if one could assume if you took the same photo in the same location by the same phone, the result would look the same, which I don’t think would be a valid assumption anymore.

Sure, no photo is unedited. But there is a difference what is the effort of post-processing. Is it none, a few seconds, a few minutes with Lightroom, or hours with Photoshop?

With enough effort you can basically do whatever you wish, especially when it comes to increasing quality (see for example this one https://gizmodo.com/deep-learning-can-now-flawlessly-correct...).

It is true that there is a difference in the amount of manual tweaking, but at the same time any remaining objectivity in “unedited” phone-produced output-referred (non-raw) images is fading fast. In other words, imagine if the technology by your link is silently incorporated in the next version of iOS Camera app without you knowing—and I’m not even sure this is an outrageous exaggeration.
