Looks good to me! I think you misspelled "wait" as "whait"

I'm assuming there are no tests needed because this should have no visible change in behavior?

whait?

I assume the equivalent of this dictionary is created elsewhere when a new pixel format is actually needed?

Yep. This is an optimization only.  I'll add something to the ChangeLog to that effect.

Nope. 'nil' means "Don't try to convert the CVPixelBuffer into a specific pixel format."  So we want this to always be nil.
