I've heard that Plex has some limited functionality in this area, but I seldom use Plex on my home network, so can't speak to it. Other than that, I no of no other app that does both. Not saying there aren't any, just I'm not aware of them.
The last time I used Kodi, the frame rate would match but the shield still kicked out 4k, not 1080p, when playing a 1080p movie. No matter what I threw at the shield, the receiver reported 4k coming in, and passed that to the projector at 4k. But that was about 18 months ago, so it could be different now. Plex, Netflix, and Amazon all seem to be adjusting frame rate properly, but resolution out of the shield remains at 4k as of the last time I checked (a few months ago). This made the idea of using an upscaler outside of the shield a pain, because I would have to switch manually to 1080p to get 1080p, and once switched, I lost 4k options in Netflix and Amazon, and plex transcoded down to 1080p when playing 4k.
This is one reason I bought the new Shield, so it could just do the upscaling internally and continue to send 4k for everything. Now that I am relying on the Shield to do this, I need it to do this all the time. I don't want it to start sending 1080p and have the JVC projector upscale as it is not good at it.
I use Plex instead of Kodi so I don't have to have Shields at every TV (last count was 7 TV's, lol, and that gets expensive). Instead I use FireTV sticks for the rest of the house, and with Kodi, half my content was unwatchable, either due to frame rate matching that the FireTV struggled with, the inability to play content over 35mbps (i.e. no direct 4k UHD), or codec issues (VC-1 doesn't work at all). Plex can just transcode it all for those TV's, and in the theater the shield handles it all direct with no issues. The only caveat to date is that the shield has to do the upscaling. That isn't a problem any more.
