Of the Play family of apps, it’s just Play Books and Play Games, as well as the Play Store, today. When Play Games for PC was teased in late 2021, Google introduced a new flatter, shadowless icon.

The new icon keeps the triangular play button, albeit with much more rounded-off corners and a darker shade of blue. The book is gone as well, survived by the white ribbon-like bookmark now ...

This icon definitely did not need the four-color treatment. It joins the new icons for Play Games and Play Console. This icon is rolling out with version 2023.5.30.0.1 of Google Play Books on Android.
