NVidia is just ugly with this.
If they really have buried this stupid Quadro-policy, I would change my mind about fancy 10bit screens.
If you are in exclusive fullscreen and on DirectX (not sure about vulkan here), then 10-bit output will work. So for gaming you are fine. Anything going through NVENC is also fine and will encode/decode 10-bit or 12-bit video.
If you have a window however and / or use a program written with OpenGL as the backbone, Nvidia refuses 10-bit color and Remote Desktop. So no 10-bit photoshop, 3dsmax or similar without shelling out for a quadro card.
To be fair, a diamond house is probably expensive with maintenance.
There is nothing you can do about it, unless you have a kepler generation card, which can be bios modded to think it's a quadro.
