Good point -- if this worked even moderately well -- e.g. it lets you capture 20 bits of DR -- a photographer could go crazy with the old film approach of "expose to the right" and simply keep settings such that every shot is "over" exposed and simply fix it all in post (it's pretty hard to over-expose by more than 6 stops unless you're trying...)
To emulate film stock we need a solid 14-bits of Dynamic range (while DxO says the D810 has it, the article below says 11-bits, but the best video cameras are getting there):
Ideally we'd get something like this AND capture polarization data as well (per the recent Olympus patent). Then you can apply polarization and exposure correction in post.
