GeForce Direct X 10/11 30-bit color support?

Based on http://nvidia.custhelp.com/app/answers/detail/a_id/3011/~/10-bit-per-color-support-on-nvidia-geforce-gpus I think that I should be able to render 10-bit color using a Geforce card and Direct X (with 10-bit monitor of course). Can anyone confrim if this is true? Or am I miss interpreting the post?
