Very often, (16:9) videos are played on Ultrawide Monitors (21:9) with black bars on the sides, in which case, the ambient lighting does not pick up the actual graphics around the video itself, and hence just goes off.
It would be great to have an option so it handles such cases by picking up the ambient colors from inside the black bars/borders.
e.g. if side bars are being recognised as the typical fillers on an ultrawide screen, then ignore them and pick up the colors next to them.
