I mean, it's definitely worse than doing it The Right Way, but it's not so awful that I want to tear my eyes off, far from it. And it's definitely a win vs. not doing anything (for unprocessed content, which is 99.99% of content on Kobo) .

On newer devices, what's done looks even better (and isn't as aggressive towards perfect content, which is a double win in my book. The clincher being that it's free on Mk. 7 (in terms of CPU cycles).).
I find the Kobo dithering interesting. On my H2O, the bit outside the circle looks really good. The bit inside the circle looks good enough. The Forma get the inside of the circle very good and outside of the circle, not as good as the H2O. Now the PW3 doe snot get anything as good as either Kobo.
