My hopefully not too uninformed understanding leads me to believe that
raw converters use a camera model specific profile of the sensor when
they do their conversion into their internal space. I am not aware of
a way to set that profile yourself in an informed way (yes one can
replace camera specific configuration files in each raw converter with
each other but that is just trial and error). Adobe's DNG converter
does something similar to raw converters. And interesting question
would be what the 'internal colour space' of DNG files is (and
possible it's rather well know, and just not by me).
A raw converter using DNG files (and not relying on the optionally
embedded original raw data) would then convert from the DNG colour
space to its internal one.
And naturally any user applied global colour-changing controls like WB
act somewhat similar to assigning a different colour space.
