I'm not sure what EVR 10bit really does inside. I think it's supposed to actually deliver 10bits to the DAC (when using analog output) or to HDMI (when using HDMI 1.3 DeepColor). But I've no idea if it actually works that way, or if the GPU dumbs it down to 8bit internally somewhere...

As long as you don't scale, there won't be any improvement, as far as posterisation is concerned, because madVR is already as good as it gets in that area. It shows exactly that amount of posterisation which is in the source. Not more and not less. The only chance for further improvements would be to either add more dither than you technically need (which would mask posterisation somewhat) or to run a preprocessing algorithm which detecs and removes posterisation from the source.

You mean adding 10bit output to madVR? Technically, if it actually worked (which I'm not sure about) it would decrease dithering noise level. I doubt that the difference would be visible. Maybe the image could feel ever so slightly more calm.
