Unfortunately the figures are wrong according to DNxHR Codec Bandwidth Specifications:
DNxHR LB/SQ/HQ is 8 bit, DNxHR HQX/444 is 12 bit! There is no 10bit DNxHR variant. So you might head into trouble when exporting HQX/444 from Resolve as 10bit. Chances are the file is not readable by other applications.
ProRes up to 422HQ is 10bit, ProRes 444/444 XQ is 12 bit!
