Am I understanding this correctly that this would be a push and rebranding of HDR10+?

Yes, if this article is correct Google will leverage HDR10+ as part of an umbrella brand (i.e. "Google Vision") for HDR and 3D audio. I'm not aware of an open/royalty-free standard for 3D audio, so Google might have to create that.
