Apart from performance, another crucial thing is that the viewer must not have to think about technical aspects (like exposure, color profile, etc.), as you noted, so the GUI would have to be radically different.

I am envisioning producers bundling N processing profiles with their “digital negative”, and software that somehow allows the user to fluidly explore the perception of the scene by interpolating inside an (N-1)-dimensional space bounded by parameters in those profiles with really low latency.
