Questions about lg smart tv intergration

hey all

i have recently been looking at getting a smart LG tv and have been looking at the integration and have a few small questions about it

-can i control the selected hdmi (switch from sky streaming tv box on hdmi1 to ps5 on hdmi2?)
-can i send notifications to the tv with the notify service?
-can i open up a camera stream view on the tv (preferably as a small pop up in the corner to see any detections at the front door?)
-(this one is a bit specific)can i set automations to open up a custom image slideshow (such as when someone is detected in the Livingroom it turns on the tv and plays a slideshow)
