Comment:
I was thinking about this issue, since dither cannot be removed in scale
in this transform (sws_dither none indeed has no effect), only in zscale
(by default no dither) that is what causes this issue, I imagine. Off-by-
one in colors must be dither. And again even the better result is still
"are mostly the same (in the start of the file), " in the end it is
different anyway, so that means it is dither.
