Correct, and you can not compress the scene's range into that of the imaging
sensor.

I disagree.  The idea of N-1 etc. development is to compress the image
density range to fit within that of the films (via both exposure and
development), and you can't do that with a digital sensor.  Data that is
beyond the capture range of the sensor is simply lost.
