Why not ask for a 3D gamut viewer then 
On a more serious note: do you expect to do any measurement on scopes? That’s not really what they are intended for afaik. Though, the outer ring in Resolve shows some angular markings, so maybe there could be a use case for that.
@priort While comparing to Resolve can be useful, what tools would you expect to use in a photography oriented scope? Do you need such fine-grained control?
