HDR metadata primaries mixed up

It may be an error in the sample code, but it doesn't seem to be. The Capture Preview sample app shows HDR static metadata, but the Rec.2020 primaries displayed here are in GBR order, but labelled as RGB:

Apologies. I think it must be my source which is outputting incorrect metadata. When I use Resolve as a source, the order is correct.
