TWRP backup is a good place to start - but on Bootloader Unlocked devices only.
See the Freaktab forums and already mentioned Nvidia Shield forums.
All the Google Certified legit Android TV - AMLogic Chipset devices have encrypted bootloaders - so no rooting possible.
Having said that I heard passing mention of Rooting - via a FireTV rooting method - of the new TiVo Stream 4K dongle over in the TiVo subreddit. Big Maybe.
There is a full userdebug Oreo 8.0 rom for Xiaomi MDZ-16-AB.
There is a partial userdebug Oreo 8.1 rom for Xiaomi MDZ-22-AB.
These roms facilitate administrator level access to normally hidden internals.
Hit me up if you want details...
You need root access and an unlocked bootloader. The Shield has an active community over on xda which is a good place to start.
Other devices (like the Mi box) may have root exploits, but none of the Sony TVs do.
