> Porn, obviously, though if you look at what's popular on civitai.com, a lot of it isn't photo-realistic.

I don't have an argument to make on the main point, but Civitai has a whole lot of structural biases built into it (both intentionally and as side effects of policies that probably aren't intended to influence popularity in the way they do) that I would hesitate to use "what is popular on Civitai" as a guide to "what is attractive to (or commercially viable in) the market", either for AI imagery in general or for AI imagery in the NSFW domain specifically.
