An example is the AMLogic S905X / S905D devices that do 10bit > 8bit < 10bit transformations via Linux Kernel dithering and rounding.
If done properly like on the S905X Vero 4K you do not get major color banding issues.

There is no difference between Vero 4K and the LibreELEC nightlies on a cheap S905X. CoreELEC and community Amlogic LE have bad dithering. I am not sure whether there are 10-bit >8-bit>10-bit conversions in the newer or patched kernel for S905X devices. The output has 1-bit accuracy. It is hard to get that if there is 10-bit to 8-bit dithering.
