Bill Claff has posted the dynamic range measurements for the A7R6 at photonstophotos.net. Below it is compared to the faster stacked sensor of the Z8 and to the mini-MF sensor of GFX100II:
You did not show the a7rV, but it looks like the a7rVI has significantly better low-gain IQ, and is about 0.2-0.25 stops better in high-gain. That makes sense in keeping with the general purpose market and having great IQ in the studio. Surely this sensor will eventually be used in other Sonys and Leicas, etc.
I'd rather they had used the stackable sensors more to improve readout speed, since I'm usually at 400-3200.
