Why are my Samsung app icons rounded while others aren't?

[AC Question]

I just recently got the new update to android 5.1.1 and I don't know why, but the app icons for Samsung apps are circular while others for Google, etc remain rectangular as they were, pre 5.1.1. Is there a way to revert the circular ones back to what they were pre update? Because quite frankly, it looks disgusting.

I'm not using any launchers or themes.

Got the same thing here after updating to 5.1.1 on my S6 Active. Looks weird. ...

Thanks for the info but what were the developers thinking by only changing SOME of the icons. Looks bizarre that way. Why not just change them all?

They can't because other applications are not under their development

Oh.. you'd think they would want theirs to match others.... Maybe they are trying to get others on-board with their choice of the rounded icons.
