[ubuntu] Xerus Wallpaper/Background. White and Grey? Really?

My 16.04LTS Beta systems, after the 4/7 keel freeze, got ubuntu-wallpapers-xenial in an update. /usr/share/backgrounds/Xerus_Wallpaper_Grey_4096x2304.png is a Xenial wallpaper? It is boring, freaking white and grey, versus the super awesome purple/red/orange of warty-final-ubuntu.png. Please say this is just for the Beta or pre-RC freezes. Anybody know what the release-default-background will be? This is crucial!!! My systems won't work if I can't link to a cool Xenial background! I can't wait until 21APR, I need it now! ')
