You can run native apps from Kodi.

I used to launch Steam games in Big picture mode from Kodi just fine.

Actually I was waiting for a desktop environment like this Plasma Bigscreen for a while but then got a new TV with Android and use that instead.

I would still prefer to use Kodi as the main app launcher on Android but it gets Killed to save memory and takes a while to start up again.

And using Kodi over HDMI is not an option anymore since a lot of content I watch comes in 4K 10bit HDR or 4K Dolby Vision and sadly desktop Linux does not support HDR and variable refresh rate over HDMI (so Linux Steam experience also bad).
