And so on came the 10-bit monitors touting 1bln colors, very far over the human eye's limits and normally, no banding should happen there. There's quite a few of these monitors on the market right now, and I'm pretty sure in the not-so-distant future, 10-bit OLED (or Quantum Dot at least) monitors will be the norm with 100% adobe RGB (or better) color accuracy and probably also HDR rendering, cus why not. I'm basically just waiting for an affordable quantum dot 10-bit display to come to market so I can buy it, because I for one really hate banding.
I'm pretty sure if you have a 10-bit monitor, banding will start to be much more noticeable, something that you normally don't see popping out in some media, like in that picture example (it probably won't be that bad, but it will feel that bad), as an artist I'd like to circumvent this so a 10-bit or just 16-bit color mode would be fantastic to have, it seems to be a basic feature in many digital painting and image editing programs.

No rush or anything though, when you implement it, make sure you do it well.
