Then how does that square with your assertion (see above) that film does a
better job of rendering dark areas?

Why use a Canon DSLR in order to make a proclamation about shadow detail
recovery?
Canon's latest FF camera has two stops less dynamic range than the
competition at base ISO due to read noise from the sensor. The D800 has
better DR/noise characteristics at ISO 800, than the 5D3 has at ISO 100.
At ISO 3200, the D800 has about the same DR as a D200 at ISO 200.
