For me, this isn't a problem that the explanation is redundant. I agree that --format:<string> is quite poor, as type alone does not give readers any information on what it means and how it is supposed to look like. Calling it <format-string> does make quite a lot of sense. It is a bit less obvious how much value we get out of <bool-value>, though. In --opt=<arg> scheme of things, what comes after '=' are all <value>s, so <bool-value> does not clarify over <bool> like the way <format-string> clarifies over <string>.
