Yeah, the images I posted weren't supposed to be definitive or anything, they are just a rough example to give you an approximate effect and get a sense of the palette and details. It's more to demonstrate that just by using automated player settings you can recover the colours to their original form. The biggest problem though will be noise, because when you start boosting colours like this, even if you don't go as far as I took them, you still get noise in some scenes, or even just in specific shots.
