OK, so there is no perfection to be had from one single device. Is there perfection to be had by combining two (2) devices?

For me the ATV 4K is the perfect DRM streaming device, and AMLogic boxes running CoreElec play pretty much all of my locally stored content (apart from niche 4:2:2 stuff that most people don't have to worry about), though the Pi 4B is now looking interesting for this too with the latest LibreElec Nightly builds (and they are running mainline kernels, and have far better support than ODroid with their comedy warranties and support)

so pi 4b can now playback of 4k HEVC 10bit HDR videos smoothly and have the same performance as Odroid N2+ and nvidia shield pro etc?

I got a pi3b with LibreElec, it is good kodi device
but lacks 4k playback and sometimes randomly reboots 

Do you have pi 4B and is there any heat throttling issues (as reported)?
