10 bit HEVC as used in domestic situations (i.e. 4:2:0) is usually referred to as "HEVC Main 10" - not "Hi10p" (as it is a main, not high, HEVC profile?).

I think you're right. I specifically avoided using "hi10p" for that very reason - if you look at my posts I always say either "HEVC 10-bit", "10-bit HEVC" or "HEVC (Main 10)" (capitalisation may vary) - except one case where I shortened it to "10-bit" when it was already in the context of HEVC. But I see that I quoted Milhouse using "hi10p HEVC" in the reply that fritsch then replied to ...

In any case, I think my mystery is solved in that my hardware doesn't support it - guess I'll have to upgrade to an Apollo Lake (or newer) HTPC at some point. I picked this NUC up very cheaply, so if I only get a year or two out of it that's fine (and it'll get repurposed anyway).

FWIW this NUC is capable of playing back 1080p h.264 (High 10) i.e. hi10p via software decoding without skipping. It's so close to being able to handle 1080p HEVC (Main 10) but just falls short.

And I do appreciate the reduced banding from h.264 (High 10), although I understand you can get almost as good results by using 10-bit internally in the encoder and output in 8-bit (to avoid compounding banding errors at each stage of the encoding).
