While most of the corrections are an improvement, this one looks substantially worse. Instead of "mystical swamp", it's "mud puddle with oppressive blue haze".

Does making the Hoth scenes less blue somehow make Dagobah less green and more blue?

That's because the Original Release was blue in the first place. How people seem to envision the look of Dagobah intending it to be green was a misinterpretation in the first place. Even Ady has explained this.

All I have to look at is the GOUT, but even there, the haze in the top of the frame is more red than blue.

I think that he did a good (if aggressive) job removing the unnatural green in the foreground, but it introduced an unnatural blue haze in the background. Just look at the top right of the image; in between the vines there is an ugly blue glow that doesn't exist in either the GOUT or the blu-ray. You can't tell me that those vines are supposed to look like that.
