well, the update to 9.0 and DV for xbox didn't come without issue. before the update i could watch certain programs on netflix with the xbox one with no problem, just HDR, but now, i get them in DV, but, they don't display properly, here are the titles i tried that i noticed didn't display properly:
Cloverfield Paradox DV
Love Death & Robots DV (mostly animated)
Next Gen DV (animated)
Godzilla P1,2 & 3 DV (animated)
Blame DV (animated)
Ballad of Buster Scruggs DV
here is a shot from Cloverfield Paradox DV, click to enlarge.
it shrinks down into the upper left hand corner of the screen, the same is true with the other titles listed. sorry about the crappy phone picture, but, you get the idea.
despite how it looks, it shows perfectly in that tiny "window" and it's the entire movie. it has only happened with the titles listed. don't know why either, but it does. for all other DV programming on netflix, via xbox one, they display properly.
i also noticed that everything on netflix that says Ultra HD 4K now is shown in DV despite the netflix banner saying Ultra HD 4K and there isn't anything wrong with it's appearance or it's aspect ratio unlike the titles mentioned above.
i also noticed all my games played fine on the xbox, i did notice it now automatically switches the tv to "game mode" when playing games and it didn't do that before the update to 9.0
when watching netflix via the 6 series direct (Roku OS) all the above mentioned titles show properly.
wondering how other users of this tv and the xbox one is and if it's similar to mine. i really watch netflix on my xbox, but, until the netflix app at large gets the ATMOS update for all systems, it's the only way for me to get ATMOS audio via the xbox. so, i do watch some things on netflix via xbox one for that reason.
