Interesting, which version of GeoServer are you using? We have had specific
performance optimizations for the "render a polygon much larger than
screen" case for a few releases now.

Yes, the JDK rasterizer does not expose gamma to the programmer, so we
cannot control it.
The workaround you are using is correct, what I think it's happening is
that the opacity is getting
used, but the two lines of adjacent polygons overlap, making the border
darker in the overlap.
