The dt manual says:
"Where an image has been captured in a raw file, the input color profile 
module will normally apply either a standard or enhanced color matrix 
*specific for that camera model*, ..." (emphasis added).
(https://docs.darktable.org/usermanual/3.8/en/module-reference/processing-modules/input-color-profile/)

Unless you know what you are doing, stay away from the fixed colour spaces 
with raw files.

Thank you for your answer, but i am a little bit confused. In the input
color profile i can choose between standard color matrix, enhanced color
matrix and different fixed input profiles (sRGB, AdobeRGB, Rec2020,
etc). But i cant see any camera specific color profile. Is the camera
specific profile 'under-the-hood'?

The camera-color space to working-color space transformation is done at the
input color profile module (
https://docs.darktable.org/usermanual/4.0/en/module-reference/processing-modules/input-color-profile/).
DT ships individual color profiles for all supported cameras, but you can
also provide your own (for example, there are people that profile the
spectral response of their cameras with spectrometers...)

Is there any point in DT where the different spectral response of the
Bayer-Filters of different cameras considered, or does the conversion
from raw-data to RGB-data treat all cameras equal?
