Thanks for updating this, Tomas. I figured the mpeg might be retaining slightly less dynamic range then the jpeg, and I guess it is, though the difference is small enough to be largely inconsequential. 12 stops of dynamic range is definitely nothing to complain about, and would be hard to better -- the m4/3 sensors on the inspire x5 line probably only get you about 1 stop more if shooting in raw/prores.
It's nice to see dlog is now a useful tool again, even if it has downsides (like color compression and subsequent banding when grading) that might advocate against it's use in every circumstance.
