I understand you would like to know if the Intel® NUC NUC7I5BNK supports or not 4K@60Hz HDR playback.
Yes, the graphics controller that comes on the Intel® NUC NUC7I5BNK supports 4K@60Hz HDR playback through HDMI 2.0 and Displayport* 1.2.
The 4K@30Hz is just a limitation for HDMI 1.4. The Intel® NUC NUC7I5BNK comes with HDMI 2.0a port.
Let me know if you have or not any other inquiry.
