Probably nonsense because the BVRAAM was first shown in 2021 (ie long before DPRK involvement in the ukrainian war) and likely it's development started before that. If there anything vaguely russian on it is the fact that actually those rear fins remind me of those on R-24.
I think the fact that the new DPRK AAM look closest to the PL-12 and PL-10 makes it possible there might (i emphasize, might) be a degree of chinese involvement, especially since the missile fired seems more like a PL-11, but we can only speculate atm.
