A variety of shows on various platforms which may be of interest,some good choices - though have not seen some yet.
Word also that HDR will be coming to Sky Q in the next few days, originally posted on the TV section. https://eu.community.samsung.com/t5/TV/KS-OWNERS-ONLY-Sky-to-introduce-HDR-content-on-Sky-Q
Virgin Media had HDR earlier (French Open tennis available in that format last year on the platform via Eurosport), but not aware there has been a great deal of content on Virgin Tv. HDR is not available on Virgin's prime app on the V6 https://www.virginmedia.com/help/virgin-tv-watching-4k-ultra-hd-content (Have Skyq but have never been with Virgin myself, though they recently moved into area) Skyq have the Netflix app on their platform (an integrated package is available if desired ) https://www.techadvisor.co.uk/how-to/entertainment/netflix-on-sky-q-3683935/ though no date no link up with Prime,obviously available via TV app. Disney Plus recently became available direct though https://www.sky.com/tv/disney-plus
I will add Joker and Ghost In The Shell to my to-watch 4K list (which is getting pretty long now).
Happy days for Sky Q owners!
