Unexpected: Nikon Z6III’s new semi-stacked sensor shows poor dynamic range performance compared to Sony A7IV

The newly announced Nikon Z6III is the world’s first camera using a “partially” stacked CMOS sensor. The goal of this design was to offer some of the benefits of a stacked sensor without all the expense. But this appears to come to quite a great cost in Image Quality:

Bill Claff from PhotonsToPhotos posted the Nikon Z6III dynamic range test results and up to ISO 800 the Nikon lags clearly behind the Sony. At least 1 stop less performance and at average ISO even 1.5 stops less! Looking at this perspective, Sony has no reason to rush the launch of the Sony A7V. Now, I am realistic enough to claim that a camera is more than just Dynamic Range and the Nikon has certainly many other cool features people can like. But the dynamic range performance is so inferior to that of the Sony that I think this may be a knockout criterion for some possible buyers. What do you think?
