It looks like it's managing to activate all the blue subpixels (which happen to be staggered for you each row right in line with the dithering), and then the reds and greens are staying partially activated past the end of the image. Something to do with how each row shares a common anode or cathode, and some current is leaking through when it's not supposed to? Not sure.
Funny thing is dithering was supposed to look better on old CRTs, especially with RCA composite video rather than separated component signals. Both of those technologies had a tendency to blur or spread the color around, which is actually helpful in this case. Seeing each pixel sharply rendered on an LCD or OLED display actually goes against the intentional blending the artist and original viewers would have seen.
