From our experience filming in Cartagena, the dynamic range is about 1 1/2 more compared to the f55, especially because of the improvement in the signal-to-noise ratio, but I would highlight two important improvements, the first is that the way in which the detail disappears in the high lights is much softer than previous cameras and second that skin tone is now more natural, with more texture and with a great gradations of color with a lot of subtlety.
We recorded in X-OCN ST corrected in Davinci  in ACES leaving in 2020 PQ 1000 nits and also in 709.
