OK, I got some numbers wrong.

If your 16bit value was 0x3000, then the 10bit would be 0x0c0 and the
6bit would be 0.
The PWM output would be 192/1024 for all cycles, so there would be no
dithering.  But 192/1024 is exactly equal to 12288/65536, so no
dithering is needed.

That's what I get for doing hex arithmetic in my head!
