I still couldnt understand if source has 16.7 million color, what is the benefit to have (10 bit per channel) billion colour monitor?

The source has more than 16.7 million colors.

if the source has only 16.7 million colors, though, additional bits on the monitor help because the distribution of the bits is different. That's what a monitor profile does. It maps out the distribution of the bits. With only 8 bits, the monitor profile could result in two colors mapping to the same monitor color, thus creating banding. That is visible on this very website. There is a sort of spotlight on the black background in the upper left corner. Calibrating a monitor can result in that spotlight getting posterized if the graphics is only 8 bits.

Unless you have an IPS or better monitor, you're using 6bits + dithering.

262,144 actual colors.
