Hey Nick,
Raw most definitely has a color space, though it is specific to the camera. It not one that is directly viewable or necessarily complete, but it is a color space. What I am not sure is if it's a scene-referred space or not.
As a color space consists of three components, chromacity primaries, white point and gamma. Of those, the latter two are configurable during the raw processing step.
What would be awesome is a block diagram from BMD explaining the signal chain in Resolve.
As I understand it, the raw settings in resolve allow you to select how to transform from the CameraRGB primaries into either Rec709 (same primaries as sRGB), P3 and BMD Film. At the same time you also select the how to transform from the scene whitepoint to the display color space whitepoint along with a chosen gamma.
After that, all of the grading takes place in the chosen color space through to output.
Based on John's comments it would appear that grading in P3 could offer some potential benefits for a DCP output.
Cheers,
Andrew
