I don't really know how to quantify how much of a percentage of a game graphics are. It changes with genre. For a QTE game that is all about getting you immersed to the point where you feel the decisions of the characters weighing on you (Heavy Rain) and for cinematic "holy crap!" moment games (Uncharted) they're fairly important (though gameplay ties into those aspects as well), but for open world stupid fun and quirky platformers they're not important at all.
