Nah the thing is, I know a bit more now, it's a linux thing - linux needs some work before HDR is ok - it's a little way away, then Kodi has to add it.
I'd be surprised if we had HDR in less than 18 months from now. After then, maybe a good chance?
By then, a new, low power NUC might be out with HDMI 2.1 too, so win win.
Gotta go without I guess.
