I would say that I care very-very little about small refinements in visual fidelity (and I find them to be a rather lazy direction to progress the games in, mechanical, as opposed to creative work - instead give me amazing AI, interesting new genres, higher interactivity, depth, better plots etc.)
Having said that...
The statements is outright false, considering that "nobody cares" is a very grand and absolutist statement to make, and is easily disproved by polling first ten gamers you'd come across(remember, just having one who cares, makes the statement invalid).
