Wouldn't that be nice! The following white paper discusses why this ideal is
often not accomplished:

I agree. And often, photographers use the word "accurate" and that's not
defined (nor do we know what it means). Is a scene shot with Velvia more
accurate than that shot with Ektachrome? Accurate to the measured color of
the scene, our memory of the scene? Pleasing to the artist (or client)?

ACR's Histogram will certainly clue you in via it's saturation clipping
which space is more appropriate to encode the data into. But that's way past
the point of rendering the scene.
