Depending on what you mean with "gain", this is not correct.
(Your sentence is equivalent to "intra-only codecs have 
no real disadvantage over using P and B-frames for 
sufficiently small fps." And this does not even take 
into account that I suspect ASP compresses better than 
jpeg even for images.)
