[Update] The Samsung Galaxy Wide 2 has also received the Android Pie update (version J727SKSU3CSG3).
The new build carries version number J720FDDU4BSG7 and requires a download of around 1.3GB. It comes with the July security patch as well as One UI 1.1. The update includes Night Mode and Digital Wellbeing, but it doesn't bring in all the Android Pie and One UI features to the phone.
