This seems fairly comprehensive: https://www.pocket-lint.com/tv/news/sky/152341-how-to-watch-hdr-on-sky-q
I'm an early adopter (May 2016) so obviously have a 32B0, so no HDR for me.
Doesn't bother me right now as very limited content but, if and when they start adding HDR to all the movies, it'll become a bigger issue. Contract is up in Sep so we'll see where we're at then.
I was an early adopter as well and 32BO58 is mine and in the same boat.
I did ring Sky earlier tonight though. The guy i was talking to was very knowledgeable and seemed to know straight away what i was talking about. It all fell down though after i said i wanted a new Q box. He put me on hold so that he could talk to his manager. They were ok with replacing the box but only with an engineers visit.
I explained i was more than capable of replacing it with no visit at all, just send me the box and i'll send the old one back. Point blank refusal to do that. Ok, send an engineer than, can't do that sir during this time. The next bit of the conversation was the most interesting though, he said that all boxes that needed to be replaced would be over the coming months according to the info he was looking at. So maybe they are thinking about just sending new boxes in the next few months, rather than the ridged engineer only replacements.
