Full RGB 2160p@24Hz

Is it possible to confirm that full RGB should be working on the latest NVidia drivers with the GTX 960 with a 2160p@24Hz (23.98)?

My Samsung TV is converting the signal to 4:2:2 subsampling and then back to RGB for ultimate display and I can’t seem to help them understand that interpolation is not something I want and furthermore has nothing to do with colors. At refresh rates of 30, 50, 59 and 60 I am able to achieve full RGB.

Please correct me if my understanding is wrong and this is not possible with either the TV(JS8500 with UHD color turned on) or the video card.
