Roller shutter icon status display adjust switching threshold and colour

normally I have all shutters closed between 3 and 10% depending on the room.
However, the shutter icon does not yet show me the “closed” status.
Can I set somewhere so that the closed status is already displayed at less than 10% and not only at 0%?
Is it also possible to change the color of the icon so that it shows open in red and closed in green?

Thanks for your help!
