Im using gtx 1060 6gb but do I need a workstation GPU like Quadro P2000 to get 10 bit color support?
Even though 10 but colour may work, but Nvidia said currently is not supported in their macOS driver.
For your info, I am using 1080Ti.

So how to use a 10-bit color monitor?
I used the BlackMagic Intensity on a 3,1 for FCP briefly, IIRC it could handle 10-bit. The trick is that the connected monitor does not act as an extended display that's handled by Mac OS itself (which requires graphics driver). Their DeckLink lineup uses similar approach and are supporting more modern applications I think.
Notably most "10 bit" displays are 8 bit using FRC, which does simulate to a degree more hues, but I don't know of any sub grandish 4k displays sporting true 10 bit. I just put in for a GTX 1060 so fingers crossed we'll get 10 bit support but most of us probably don't have true 10 bit panels so not missing as much.
