Midjourney very much has a style and like looking at the front page of ArtStation while the images are of a high “quality” in the technique sense, the artistry of them is pretty low.
Very rare to see an image that will surprise you on ArtStation, just a sea of orcs, elves, guns and spaceships in the same “painted” yet completely uninteresting style. Same for a MidJourney output, all very safe, all the same tricks to provide “impact” yet all utterly boring.

This leads me to believe that a lot of people may share your view and thus steer the upcoming popular visual styles into the opposite directions (the pendulum). Maybe more abstract / gritty / grunge / minimalist or messy. I've seen a similar development in music and it steered the popular audience to the stoner rock genre for a while, simply for being the opposite of the currently popular in multiple ways.
For example - if you prompt "low poly castle, isometric". The output wont't be low poly or isometric, but something that "looks cool".
This is why people are hyped about the new SD XL. It understands prompts much better than previous iterations of SD and Midjourney. And it can be customised and extended. Can't wait for the full release, Controlnet XL and other extensions.
That's because of default settings, it's not a limitation of the model. I get Midjourney magazine for $4/mo; curated examples are quite amazing.
A better comparison is this vs artstation.
