The over contrasty, shiny image in that screenie is easy to fix.
1)Turn HDR off in the options, the contrast levels end up way too high.
2)Adjust the gamma levels with the options menu sliders, with HDR off I have it set at default.
3)Desaturation can be tweaked in the startup.cfg file in the ROF/ data folder. 1.0 is default, I like the desaturated look so have it set to 0.75.
4)If you don't like the Bloom, with HDR off I do, then you can turn it off in the options menu.
Screens with HDR off, Bloom on, saturation 0.75, gamma default.
