Thanks, applied, compiled and success.

But one strange thing - with your patch for kernel 4.4 to have correct colors with no banding I had to choose Full range. Now with this patch and newer driver in kernel 4.9 I had to switch to limited range. But once I've done it IMHO final result is better than it was with kernel 4.4. No banding at all (in 4.4 it was sometimes visible). Thanks :-)
