Initial BlackBerry 10 slides and first looks showed the OS to have square app icons. Then, BlackBerry changed their minds and allowed for non-uniform icons for apps, but had a gray transparency behind the icons.
Many users have voiced their opinion of distaste towards the look of the icons. I even tweeted that I wished BlackBerry would allow for an option to toggle the backgrounds back in August:
I wish I could toggle on/off the shadow behind icons or at least edit its transparency in BB10…

It seems BlackBerry has listened to such feedback. According to a tweet from BlackBerry product manager, Michael Clewley, BlackBerry will allow the removal of the gray transparency behind apps in OS 10.2.1.
@jareddipane yup. 10.2.1

It will be interesting to see if BlackBerry has completely removed the gray transparency or if in fact you will be able to toggle it on/off. Or, give it even further customizability with changing the transparency level and/or changing the color of the background.
