Question about Chromecast TV display


I think that how my now playing screen has changed recently, the screen used to be separated into what I would describe as two coloured zones vertically, now its three:

See the grey area at the bottom then the darkened see through area above that then the actual picture of Beck. It used to just be the grey at the bottom and then the Artist picture with no inbetween section.

I wish I could describe that better, does anyone know if what I am seeing is correct ?
