So, I understand that 8 bit panels can do 16.8m colours (256 x 256 x 256) and a 10 bit panel over 1 billion (1024 x 1024 x 1024).

How does the Samsung KU with an 8 bit panel, support a wide colour gamut ?
Clever algorithms to 'fake' 10 bit ?

Update 11/09/2016: Our original test was showing 8 bit gradations due to incorrect drivers on our system. After some correction to our test apparatus, we have retested the color depth and found that it is able to display a 10 bit gradient smoothly. There is some little imperfections in the darker green, but nothing that could make normal viewing problematic.
