FYI: UHD is rolling out on Google Play Movies now. It's not showing for me yet, but is for some.
I have yet to really look at digital UHD options since I only have a 1080p pj, but I was wondering, for other services that been offering UHD, do they let you buy the UHD and get it streamed, but downscaled to 1080p for display? (thus getting the higher bitrate, bit depth, color gamut, 4:4:4 chroma?) I have the Nvidia Shield TV, so I'm wondering if I can get some added benefit from UHD Google Play movies even on a 1080p pj?
