The below screenshots are from version 7.3 of the Google app, the latest UI is somewhat similar to the Google Now panel you have right now, except the background is now transparent and shows the current wallpaper underneath the shortcuts and cards. The Google logo is no more and the search bar has been moved to the top.
That said, Google seems to be testing or maybe rolling out the new transparent Google Now panel UI. So far, only a few reddit users has reported these design changes. Anyone else seeing it? Let us know in the below comment section!
