Newer LG TVs: Turn screen off function
My LG C2 has a dedicated menu point for turning just the screen black/off. This will make the tv stay awake but just black out the screen. I use a 42" C2 as my monitor and it would be really nice if i could build an automation which just turns the screen black. 

The command should be:
com.webos.service.tvpower/power/turnOffScreen

Could this be implemented or is it already and i just missed it?
Thank you!

EDIT: Found it! Thank you!
