Just to toss this out there, with my BMPC 4K attached to my Macbook Pro via thunderbolt, Ultrascopes gave me a better visual for what's happening.
From ASA 400 to ASA 800, the histogram doesn't change the top level (at 80 IRE), but it does raise the low end quite a bit. It also affects the mid tones. To me, the higher end is squished in the histogram when raising from 400 to 800 since it's stopped there. From what I recall, going from 400 to 200 shifts the mid tones down more (possibly bring back some of the congested detail in the 80 range, but can't be sure).
