I'm skeptical that cameras can be adjusted to render colors exactly as the photographer sees the scene.
In all but the very fewest situations, the physics of light render it impossible to produce an image that is exactly like the captured scene. If I capture an image of my sofa, it's impossible to reproduce the exact same look when displaying the photo on any kind of light-emitting display or on any kind of printed media. That's because the medium that we use to display the image projects or reflects light differently than the sofa's materials.
Personally, I don't see color accuracy as a goal
I also don't have that goal, but that's only because that goal wouldn't fit with my style of photography.
If we're going to get into the realm of philosophy, what is the true color of an object? As an example, we can easily make any object to appear black, white or anything in between simply by lighting it to make that happen.
