To me, that's not reflecting reality. A story reflecting reality would be commenting on Ukraine, or Brexit, or Trump (or veiled references to such). Commenting on the human condition is something much more nebulous, less bound by time or events or reality.When I say that art reflects reality I mean that it has something to say about the human condition.
The Iliad and Odyssey, which you mentioned earlier, are not meaningful because they reflects reality, but because they do not. Witches and mermaids and cyclops and endless journeys where all seems lost — these are not reality for most people, but most people can find meaning in the story because people can see analogs in things they do see as reality.
The friendship in The Lord of the Rings is not reflecting reality; it's displaying what friendship could mean, and allowing the readers to think about what friendship could be for them. The dystopia of 1984 is not reflecting reality; it's displaying the possible dangers of a controlling government overseeing every aspect of our lives, and allowing the readers to think about whether to be concerned about what their actual governments are doing.
One type of story might recount the events of the murder of George Floyd. That's a direct representation of reality. Another story might talk about police brutality. That's a layer removed from reality, even though it is also a real thing. Another story might talk about authoritarian injustice, which is yet another layer removed, and could apply its commentary to a large number of topics, many of which would have nothing to do with police (anything from family dynamics to countries' dictators). The further removed from reality, the less topical, and the more meaningful the writing becomes.
It is not about the story reflecting reality. It's about seeing your choice of reality through the lens of the story. Perhaps you like the lens, and perhaps you don't. Perhaps you like the view it provides on one topic, but don't like what it suggests when applied to a different one. Is that because the lens is flawed, or because your own biases are flawed? A well-crafted story will give you lots of ways to look at lots of things, and many people will want a story to be useful for looking at specific things that they are particularly concerned about at that point in time. But one person's view (even the author) does not prevent another person from taking a very different view, and both being valid.
The same story may seem to be indicative of different concepts to different times, places, and peoples (for example, with your X-Men example, that can also be used as a perspective on gun ownership, government regulations, education, etc). But "reflecting reality" serves only for documentaries and topical discussions, not stories.
