Considering post processing algorithms to compress signals and clean electronic noise etc... another possibility to consider is at which 2 ISO settings, Nikon has designated to use higher gain in the ISO 64 sensor. Testing by Bill Claff should reveal these settings, and see Jim Kasson's correction to Nikon's answer in an interview after Z9 launch:
"Apina-based technology allows optimum suppression of read noise at two ISO settings which are determined when the sensor is designed. If the Z9 [sic] is to be a high-ISO monster, it will make the switch to high conversion gain at a high ISO setting."
The original Nikon answer by an interviewee:

Does offering a base ISO of 64 come with any trade-off in high ISO image quality performance?
By adopting dual conversion gain technology, it is possible to suppress noise to the utmost limit at each ISO sensitivity from low ISO sensitivity to high ISO sensitivity, and expand the dynamic range. The Z 9 not only inherits the minimum ISO of 64, but also achieves an expanded shutter speed of 1/32,000sec, further increasing the creative potential of fast lenses such as the Noct or the Z 50mm F1.2 S.
For example, when shooting outdoors on sunny days at F1.2, optimal exposure, as well as under-exposure for low-key images, are possible. Low sensitivities are required when F1.2 and other fast lenses are used at maximum aperture. With the Z mount system especially, a group of lenses including the F0.95, F1.2 and lenses offer rendering performance that enables worry-free use and maximum sharpness from maximum aperture. Nikon designs with an emphasis on resolution, which is something that can be felt in comparison with all other manufacturers, and is a place where Nikon has a distinct advantage.
The pixel count of the Z9 is the same as the Z 7II: will the Z 9 be able to deliver the same image quality?
The image quality of the Z 9 is superior to that of the Z 7II in a few different ways. For still images, the faster scan speed minimizes rolling shutter distortion. Additionally, there is also improved stability in automatic white balance, and improved rendering of sunset scenes through higher performance of natural light auto WB.....
...Compared to the high sensitivity of the Z 7II, the noise in the flat area is particularly low. Compared to the D6 used by many sports photographers, the Z 9 is better suited to the [needs] of a sports photographer who shoots with a need for cropping, since the number of pixels is large. Additionally, when the high-sensitivity noise reduction is set to Strong, the roughness of the image can be reduced.

So reading the above i wish only for the Z9 to deliver NOT LESS than the D850 in image quality and dynamic range, using Raw, or JPEG fine at maximum 20 fps.....
So is that what is being said or questioned.............
I want to shoot the Z9 just like the D850, with the option of utilizing the speed and other benefits...........at a flick of a switch.
I intend only using the Z9 around 10-12 fps with the option of moving to 20 fps if and when needed...............for special applications.........
I am looking at the Z9 to be my all round do everything from landscape to sports action and wild life..........
a) i cant really ware the shutter out
b) i get IBIS using FX lenses but limited to only 3 stops not 5 for Z lenses???
c) tilt screen
d) 45mp at 20 fps is handy...........
e) tracking is a free bee i am not really dependent on that so much i like to use my own skill set.............or be in control,
Number one is unless the image quality is as good as the D850 i don't want the Z9............
Ok the bonus is 30 fps, heck only knows if i would ever even use 120 fps LOL
