The NUC7CJYH does not have 10 bit support as it only has an Intel 600 GPU, hence I think you are incorrect when you say it has 10bit support. Yes, HDMI 2.0 does support 4K @ 60Hz.
The Vorke V5 is a much better product, providing 10 bit (GPU 610) AND 4K 60Hz via the DP.
EDIT: My bad, HDMI 2.0 does support 10 bit. Sorry.
