They rate what they call Photo DR at base ISO (or max DR) as follows:
Pentax 645Z - 11.75
Nikon D810 - 11.53
Sony A7rII - 11.38
Pentax K1 - 11.36
Canon 5DsR - 9.79
These look accurate from what I've seen.
The gap between 11.36 and 11.75 is just over 1/3 a stop difference. That's basically the manufacturing variation that could exist among 100 copies of the exact same sensor.
