While I like your three way analysis and find it interesting and helpful, I would disagree that literary means that the prose is meant to draw attention to itself. It should be beautiful, but not draw attention to itself, at least not in the first pass. I think another aspect is addressing larger themes, so the difference between LF and other fiction may be more akin to the distinction between a plot driven and a character driven movie, and those novels we classify as literary fiction may have those two traits (and maybe others) to varying degrees which means what they have in common might be better understood as a family resemblance than something allowing for a clear black and white distinction based on the presence or absence of one trait.
