No worries, I was just talking loud in my head. Wondering again, I think that new TVN looks more in line in the WS-10 path (ejector type). The J-10 TVN is further away.I wish I could answer you but I've no clue of the technical details regarding turbofan engines.

It looks like a con-di nozzle based on the interior of the nozzle. From the looks of it though the nozzle might pivot before the convergent section rather than at the divergent section.
The reason that I suspect ejector is the perceived gap if it is gap that let in air. If so it can not be a pure con-di, at least some ejector effect is in play just like WS-10.
I could not see the convergent part of the nozzle. I do see some different (small) petals at the inner end of the nozzle. Once again, if there is the gap, these small petals can not be the end of convergent section because the two section has to be connected and sealed to function as con-di.
Anyways, we need more clearer pictures and from straight back to say for sure.

J-15 model at Zhuhai shows a loadout of potentially six anti-ship missiles:
... which might mean it could be a ball joint design
Since it's apparently CGI, it may just be a generic representation though.It is conceivable to design a con/di nozzle to entrain a small amount of secondary air flow for cooling (IR signature reduction and longer service life of the nozzle components) rather than expansion control purposes. GE proposed such a solution as an option for advanced F110 derivatives at one point, but I don't believe it ever entered production.
Pretty sure it’s a photo, not CG, but that the pic was a pic of a screen doesn’t help.... which might mean it could be a ball joint design

J-10B TVC has just executed a series of Cobra maneuvers. You have to see this.
