This highlights the true problem with society. We're only concerned with immediate impact and superficial enjoyability. But the true scope of enjoyability goes beyond this: it should also be about how the story eventually effects a person. Anne Frank's diary for instance: it's a gripping story but also it informs us about the reality of an actual person.
But even in fiction this is true: eventually one learns about the author and their life and this contributes a little also to the enjoyment of a work. But this isn't measured in these studies, which ignore everything that's important to being human.
An AI photograph similary can be enjoyed more than a real one based on its visual appeal, but the real one has the advantage of informing us about the experience of the photographer.
Modern algorithms and science always downplay the human sharing aspect and focus on a single dimension, to the detriment of us all.
