How could this apply to concept art? Concept art is about communicating ideas, not about re-creating existing images or ideas in a different visual style (well, sometimes it is, but very rarely). The visual style of concept art is only relevant for certain sub-"genres" of concept art (e.g. for very stylised games where certain visuals simply don't work), and for promotional art which is sometimes misnamed as concept art.

I'd like to see that field become less awful too, but I don't see how this could help.

Also, "immaculate" means "very clean", are you sure that's the word you meant to use?
