MrMC will do this by default. Kodi can do it if set up right. That way streaming apps will output at 4K. Never used Emby so can't speak for that one. Downside is that when your stream 1080p from apps that don't support resolution switching your stuck with the Shield's upscaling. I sit far enough from my 65" screen that I can't really tell a major difference with Shield upscaling so I don't mind. Closer viewing on a large screen would be more noticeable though.
This is my experience as well. Pulling a chair up to 2' away from the screen and running text patterns, I can *clearly* see all of the flaws/failures of the upscaler that others so often complain about. It's real and its easy to spot.
But I sit about 13' away from my 75" set for "normal viewing," and at that difference it is AWFULLY hard to notice. It's certainly a much smaller difference/improvement, to my eyes, than the difference between TrueHD/HD-MA and DD/DTS is, to my ears, and many on here are adamant about the lossy audio being "good enough" (or more)...
I do think maybe PQ/tonal quality has gotten a little bump/improvement, for me, with this color space switching. I've been fortunate that for many months now, on Sony TVs like the one I owned, the color-mapping for Shield REC.2020 output of SDR content was ~fixed (the major/distinct/obvious flaws in the washed out Red of the Netflix app icon was remedied long ago). But I think having shield do the proper SDR output might be just a *little* bit truer/better... I like it.
It'll be a MAJOR improvement if no longer doing all the processing it was doing to scale things up to REC.2020 will mean it no longer needs to be rebooted once (or more) a week.... early days (1 night), but so far overall performance around the GUI/homescreen I think as improved for me as well.
NVidia's continued support of this device has been great. I sincerely hope this isn't the last streaming box they ever release...
