A:Answer First no KODI. There is a web browser. I have not tried it. Opera is also available to download.
I am using a Nvidia Shield TV Pro. Supports 4K HDR, KODI and most Android apps. You can connect wireless keyboards and most any USB devices.
Web iOS has Netflix, Amazon video, google play movies , plex, VUDU and a few lesser apps.
If you plan to buy a Smart TV and expect ito be able to cut the cord, it ain't going to happen.
The image on this tv is amazing. Add the Nvidia box,, a good 4K hard blu ray player, and a receiver with 4K. HDCP 2.2 support and you are set. My opinion.
