HDR is still a work in progress (Kodi, ffmpeg, drivers, kernel etc.).

Gemini Lake should in theory support HDR, eventually. However I would not invest big bucks in any hardware with a view to future HDR usage until the HDR software side is nailed down - things can and will change, and promises of future HDR support on specific Intel hardware shouldn't be relied upon (call me a cynic but if they need to sell new chips there's less incentive to backport HDR support to their older gear).
