Should I be expecting a lot better from my A9 at ISO 4000?

I'm sure my A7 iii was a lot better.

With DR the A7III is visible better in demanding situations at base ISO and up to about 800 ISO, but the difference levels out from around 800 ISO and up and DR starts to be basically the same on these two bodys. Around 800 ISO is also where the A9 sensor starts to be ISO invariant (meaning it isn't below that).

Color sensitivity and gradients are basically the same on these two bodys.

Noise is also basically no difference as can be seen in DXOmarks measurement in the graph above.

I have both bodys and I think DXOmarks measurements lines up well with how I experience them.

Mirrorless, mirrorless on the wall, say which is the best camera of them all?
When I put my camera in Manual mode, why don't I get any instructions?
