Everything looks like an on/off switch
i'm not sure if this is a limitation of the functions and available controls of iOS home app, but each function looks like an on-off switch slider and takes up a lot of screen space on an iphone, and every app 

is there any other way to present the UI of the tv within home?

i'm using the plugin inside of HOOBS and my config looks like:

		  {
		  	"name": "LG webOS Kitchen TV",
		  	"ip": "1.2.3.4",
		  	"mac": "aa:bb:cc:dd:ee:ff",
		  	"pollingInterval": 10,
		  	"volumeControl": "buttons",
		  	"channelControl": true,
		  	"screenControl": true,
		  	"screenSaverControl": true,
		  	"mediaControl": true,
		  	"soundOutput": "external_arc",
		  }
