Yes, my first thought was that it's a blatant copy of Lollipop.
As stupid as it sounds.....look up the issues of the law suit between Apple v Google.
Button design and Layout. Huge money just for a Home Button....also the design of the Dialer "Icon"
Now seeing that Lollipop came to Market first with the Lollipop look of the home row, and the fact that Google has been less then friendly to Windows Phone....first not building a Youtube app, then blocking the one from Microsoft.......
I don't think the design is bad, just something that should be reworked to have the official Windows Phone Icons put back.
