Well, no. To eliminate shadow banding in the image, you simply let that shadow print to black. If you wanted detail in that shadow but have to print it to black to avoid banding, that means the image has less dynamic range than you desired.
It can't have "captured a great amount of dynamic range" and still have banding in the shadows--that's the definition of the low-end limit of dynamic range: The point that you have to print the shadows to black because of artifacts in the underexposed portions of the image defines the bottom end of dynamic range.
I kind of think you missed a bit of what have been said in this thread.
Do read some of my earlier posts, questioning exactly what is the corect definition of dynamic range. The dynamic range that 95% of the pixels in the image has. Or the dynamic range where the pattern noise isn't visible.
Sites measuring dynamic range will base their figures on statistical methods that will indicate the dynamic range for the 95% pixels. And Canon's claims about the 5D2 having more dynamic range will also base it on the majority of the pixels. After all - the the image do clearly show lots of real details with a very high dynamic range.
The whole point about people being angry about the dynamic range of the 5D2 is that measurements and Canon claims are not meaningful. Just because the usable range isn't so good. Just because you have to throw away all these captured details just to get rid of the patterns.
