I see. It's done with metadata by your definition. ie. you adjust a slider and it's happening right in front of your eyes type of thing. No re-rendering required, etc..
Guys my theory on RAW baking in one of the three presets might be wrong then. It barely makes sense. Surely Sony has just chosen some baseline color temperature (native to the sensor I would think) and then everything is just adjusted in post as "metadata".
As James points out, if anything its a routing / hardware / 'oops we didn't think of it in advance' issue.
The alternative you put forward there would be a lot of Raw cameras deal with it, I believe.
