Just downloaded and started playing. Started in Oggok, it was fine. When I zoned into Ferrott, it appeared brighter, but then when i opened options it went back to being darker again.
Secondly, as soon as I zoned into Ferrott, the world was not as green anymore, it was desaturated (the ground appeared and looked as if you were walking on the moon...gray).
I will keep playing to test.

Update. Innothule Swamp appears the same...very grayed out in appearance for me. No greenish colors popping out. Not sure if it's just me or what.
Update 2: I found the issue. If there is not a light source near the textures, they all appear to be desaturated or grayed out in color. I am attaching an image that shows this. You can see the colors on the ground with light source near it.
