Hi johnnyp: Thank you very much for joining the Intel® Processors communities. We will do our best in order to provide the information you are looking for.
In regard to your inquiry, the NUC does support H.265/HEVC hardware accelerated decode with 10 bit color depth, the driver will automatically enable 10-bit when running full screen DirectX* applications that supports it on a 10-bit capable Display. Some applications and displays do not support 10 bit color depth.
Any further questions, please let me know.
