I was able to access the UHD content on the Prime Video app about a month ago. However, I've tried it again recently and do not see any of the content now. I have Sneaky Pete UHD saved on my watchlist and that works as expected (UHD HDR) but I can't find Grand Tour UHD when I do a manual search or look through the other shows.
My tv model is KD43XD8088BU
Nevermind, found it eventually
