It's much better than it was and the levels are roughly correct.

On close inspection it is not consistent, the main static pattern being 
different pixels in the corners of 8x8 all over but there are many more 
slight variations/patterns.

There are also temporal artifacts which repeatedly build and then clear.

I am observing full screen on a 1920x1080 monitor so 1:1, and didn't 
notice the static patterns at first. They are a lot easier to see after 
taking an xwd -root and then using display from ImageMagick and middle 
mouse button to magnify.
