I hate that phrase because it's completely wrong. The cover (including the title) is absolutely a decent tell of the subject and quality of a book. It's not perfect, but it's the only thing to go by.

Crappy icons pretty much always indicate a crappy app, in my experience, and can immediately be rejected. A polished icon doesn't necessarily mean the app is good though, just that it's worth taking a closer look at.
