Thanks a lot for your answer / Regards from Argentina
You can't set 4K 422 10-bit since it's not part of the HDMI spec.
I suspect you mean 4K 444 10-bit, in which case there will be no banding introduced in decoding, and this is the optimal setting for playback of UHD material.
Unfortunately on the Dune, this is output at 23.988fps which causes a frame repeat(microstutter) every 1min 23seconds approx.
Now you may or may not notice this - some people seem more tolerant of it than others and certainly using frame interpolation modes on TVs can alleviate it, usually at the expense of causing the dreaded "soap opera" effect, but again, some people like that.
Static or less dynamic imagery also hides it so you may only notice a few instances per movie. The classic "tell" is a pan, zoom or tracking shot where the motion noticeably stutters back a frame.
As for 12-bit settings, you're correct, there is no point in choosing 12-bit 4:4:4 since the source material is 10-bit and the Dune does not interpolate, it simply pads to 12 bits - so same image quality as 10-bit colour.
The only thing this does is needlessly increase the bandwidth requirement on your HDMI chain.
