If real this is indeed a major news: long expected and often shown on patches and models, but never before seen on a real aircraft or confirmed, this appears to be a JF-17 Block 3 prototype carrying dual racks with two AAMs each (looks like the older PL-12 due to their longer rear-fins)

Not bad. That means Block 3 gets an energy boost and still carry 4 medium range A2A missiles and 2 short range.
Do we know if the inner pylons typically carrying fuel tanks can also carry MRAAMs? Single centreline fuselage tank plus 6 MRAAMs and 2 SRAAMs would make this a mean air superiority fighter albeit with shorter range if it only carries one tank.
