Samsung will know that you’ve rooted your device if ever you take to service center to claim warranty.

Confirm Root Access
You must have a new app installed now: SuperSU. Check it in app drawer. However, in case you don’t see it on your phone, try installing the app separately from Play store — SuperSU Play store link.To check whether you got root access or not, use this simple made-for-this-purpose app, Root Checker.
UPDATE: Armstrong Vogel has suggested a cool tip in comments below to get rid of the Knox verification message that appears everytime SuperSU is called for action. The error message reads “SuperSU tried to access system in your device without authorization. This action was blocked”
To get rid of it, freeze all the Knox related apps installed on your phone, you can use Titanium Backup app to do that. Here are the apps you need to freeze – KNOX: 3.0; 1.0; Agent 1.0; Store 1.0 and the Knox Notification Manager 1.0.
Thanks Armstrong!
