I'm confused by this comment, some things made with AI tools are very similar to what we were seeing before but that's either done intentionally because someone really wanted to make something in an existing style or it's done by amateurs who haven't got the hang of crafting and combining prompts yet so they just use the copy/paste "in the style of" "by X" prompts.
Just try browsing the most popular images from Midjourney and you'll see a lot of stuff that stands out, and these are the popular images that most people find acceptable. The iceberg goes much, much deeper when you dig into the galleries of individual creators.
