I think they do care, it's just not something most people notice until it looks wrong. I'm not a painter-decorator, when I walk into a house I won't notice the paint colour, unless it looks terrible or clashes or something, in which case I probably will notice. There's a lot of things like that. A classic example I'm very aware of is something called "juice" in game development, which you would never notice whilst playing a game until you play one without it, at which point its immediately obvious.
