GPU SubVendor name Python

Question

I'm using pythons wmi module for a lot of hardware specs of a system.

I'd like to get the Graphics card SubVendor information. Like MSI, EVGA, XFX etc.

I have not yet found a way to do this. Any suggestions?

WMI has nothing that returns this. Searching I don't see an option for specifically the SubVendor. Name returns "NVIDIA (card model)"

I don't know how GPU-Z or Speccy gets this information. Its possible though.
