Yes, in a way. A measurement is NA if it is not applicable e.g. a color does 
not have a mass, whereas NAV is used in contexts where there is a relevant 
value but it was not retrieved, was lost, was recorded but is indecipherable, 
was recorded but was corrupted, was recorded but was eaten by the dog, or some 
similar reason.

The philosopher in me would say NA is an ontological nothingness whereas NAV is 
an epistemological nothingness.
