"Am I missing something?" or "Am I missing anything?":
I can see how there is a subtle difference in the meaning but is one of these idiomatic?

Am I missing something?
This is more widely used, colloquial, idiomatic and grammatical as well. For example:
Am I missing anything?
This is equally idiomatic and grammatical. However its usage is (quite) low as compared to am I missing something.
However I feel, something refers to a small range of objectifiable things, whereas anything indicates a far bigger range.
I'd say that something can be used in a more general way for when you are referring to any arbitrary number of things while anything would be better suited when the things are limited in numbers.
