They also have a 46 megapixel Nikon Z9 which they don't appear to have used for some odd reason...

I found one taken with Z9: https://images.nasa.gov/details/art002e009301

There are some very bright noise pixels on the dark area, which is different from the noise in similar photos taken with D5 (much darker and uniform).

A common error made with "pixel peeping" is to zoom to 1:1, which shows a smaller physical sensor area with higher megapixel cameras.

The trick is to zoom to the same percentage zoom and compare side-by-side.

I did spot a few "hot" pixels visible on the Moon, but those are easily fixed in post.
