Man, you're just missing the point. It's about the look of what happens when it reaches the end of that range. It's not how much range it has.

For example, I've seen footage shot on a Red (don't remember specific body/chip) of table top food products with fun issues. Specifically, it was a chocolate shake with whipped cream on top. The sensor had issues with the white so that when the exposure was pushed, the white became magenta. The green data was not hitting at the same levels as the red and blue. To get white, the green channel needed to be pushed independantly, but it was already clipped digitally even though the R/B channels were not.

Scanning that same image from film would not have exhibited this behavior.
