I could not find the 4k/hdr version on Prime. Strangegood review and I agree a pretty solid 8 - I watched it over 2 days - liked it and could definitely watch another season or two
picture quality was very good in 4K HDR and the 5.1 soundtrack pretty decent but it is surely time Prime made more of an effort with Atmos tracks
I assume this is SDR only as you did not include HDR label on the Review Image?
typical amazon it is there but not as easy as netflix - I found the HDR version on ATV4k, firestick 4K and the on board prime app on my LG B7 tvs - open the link and as said above i got HDR UHD on all my devices automaticallyI could not find the 4k/hdr version on Prime. Strange
We are next to our BT exchange so get a solid 80/20 with 4ms ping times or thereabouts - pretty much instant UHD on Amazon... it's greatagreed on that - star trek discovery is HD HDR only and looks really good - but alex rider starts on my B7 as HDR HD and after about 40 seconds shows as HDR ULTRA HD
probably varies on display, device and broadband speed
