It would seem that creating a camera with 3 accurate cone sensitivities, or even 4, is a solvable technical issue.
But how can one recreate the observer's white point adoption, especially in the presence of mixed light, if one does not register the 360 degree scene at high DR?
There do exist spatial color appearance models like ICAM from Munsell Color Science Laboratory. I have no idea, though, how well they perform in practice. Compared to a traditional color transformation, where the output color is a function of input color only (independent of the image, and independent of pixel location), such a model requires complex image processing (it's basically similar to HDR dynamic compression, but is not limited to luminance, but extends to color appearance).
