Question: Will AppleTV 4 do 4k HDR from iPhotos?
I am thinking of moving up to a 4k UHD HDR television set and an AppleTV 4 with the Black Friday sales. First I need to know if the AppleTV 4 drives a full 4k UHD HDR rendering of photos from iPhoto (not Photos) on my Mac computers. It isn't worth upgrading for the paltry 4k content display currently available of TV shows and videos.
iMac (27-inch, Late 2012), OS X Yosemite (10.10.5)
