In my original posting I said "if they did it right".  

As I said, I used to write inkjet drivers.  The obvious difference 
between the 2200 and the 4000 is that the 2200 produces very obvious 
patterns, which increase the visibility of the dots, and the 4000 
does not.   There are essentially 2 kinds of dithers: random dithers 
and patterned dithers.  The 2200's patterns don't look like a 
patterned dither, they look like a badly done random dither.  So I'm 
surmising that that's what needs to be fixed.
