Yay for an actual spec sheet!
While full well capacity is higher, read noise is also higher at 2 e- rms. (The BMCC is 1.5 and the Pocket is 1.2, in comparison).
So, you have to divide 40,000/2 = 20,000, of which the 20log(20,000) is 86dB or 14.2 stops.
However, the full well capacity is listed as GREATER THAN 40,000 and read noise is LESS THAN 2, so the difference most likely adds up to the 88dB claimed.
Also, global shutter mode is listed at less than 5 e- rms. 40,000/5 = 8,000, and 20log(8,000) is 78dB or 12.9 stops. However, like above, we can assume that it's going to be greater than this, so it will most likely be over 13 stops in global.
