It doesn’t do 1080p to 4K switching, but the upscaling in the Apple TV seems to be on par with my TV (it actually seems better to me).

Nice info for a quality upscaling solution

Any chance you are using the ATV 4K for deinterlacing using MrMC Kodi PVR's or similar ?
I'm interested to see how that is handled for 1080i H264 and 576i mpeg2.

I had a play with the new ATV 4K in the Apple Store last week and yes the remote takes some getting used too. It's actually too small for my Gorilla Hands.
