Do we know if the original black prototype also had the smaller pitots on the sides? I wonder if the smaller pitot is replacing the bigger one or if they serve a different purpose. Hmmm...Sorry I don't quite understand your question.
I don't think we've seen any J-20s with testing phase pitot tubes since like prototype sn 2012. Prototype and production J-20s since then have all lacked the pitot you are taking about.
And it's only in later production aircraft that we saw J-20s with the additional weapons bay dark outline treatment.
So if the question is whether the aircraft in the pictures is configured similarly with production J-20s that we know of, the answer should be a definite yes.
I.e. there's nothing on the aircraft itself that looks out of place imo
