I have a Samsung S7 and noticed there was a faint ghosting from the notification bar. But I'm not sure if it's screen burn in or an image retention, since I've read that image retention goes away after a few days.
The phone is still under warranty, but our services are really bad, so I'd try to avoid that option if possible.
