I've had a little more time to look at some of these, and they look great.
They show a fact of life for photographing an image consisting of bright spots of light with dark spaces in between, and that is that the exposure must be set so that the bright spots don't get clipped. Since part of the image area is black, the average over an area is reduced. Therefore, an object like Judy Garland's white neck bow is represented as less than full white.

There is no way around this when you are photographing the dot structure at full resolution. It does not look bad when the image is viewed by itself with no normally exposed image next to it on the same monitor; it's only like turning the monitor brightness down. If you want a brighter version, the only way is to reduce the resolution until the dots are smeared together (and also without moire' patterns), which would defeat the purpose of accurately depicting the full image quality.
