By giving them the little details, you engage the audience (well, most of them) and make the work more compelling. Medical and Crime procedurals are this in spades. Sherlock Holmes is still idolized.
Educational genres are explicitly against the Kuleshov Effect. The whole point is to get to 4. The audience is not exactly unengaged (video games are engaging by definition), but they aren't drawn in. There are no compelling mysteries or 'flaws' that they help solve with the story of the game. Just a computer holding back an answer.
