Unless you want to keep giving your money to Intel, my honest advice would be to buy a cheap ARM device as a stop-gap Kodi player and then, once HDR is fully working in the software stack, you can invest in x86_64 hardware with confidence. Right now the situation with Intel is a total mess, and still a bit of a lottery as far as even recent Gen 8 hardware is concerned.

Unfortunately Nvidia GPUs are unlikely to be supported by Kodi in future (because Nvidia doesn't support VAAPI and VDPAU support is going to be dropped), Intel CPUs with iGPU may or may not support HDR depending on Intel politics/bank balance, and AMD APUs should support HDR across the board (but as yet AMD doesn't have anything like the NUC ecosystem).
