[Feature Request] Average Screen Colour Option for Ambience Effect

I'd like there to be an average screen colour option for the ambient effect like LIFX Control Panel has.

I find the scaled average mode only seems to look the top center of the screen and screen copy looks okay but only when there's no video playing on screen.

Scaled average and screen copy are not good matches for videos and moving images especially when used with my LIFX light strips because it just turns my room into a blinding disco of colours that dont really match the video at all
