Anyone experience flickering?

I've played with all Note5's and Edge + phones on display and all of them had screen "flickering" present on high brightness and a white background, like the YouTube search feed or browser home page. It kinda seemed annoying, and I was wondering if you guys see it too. Everyone that I pointed it out to, saw the flickering. It's not bothersome, but I am wondering if it can get annoying under lower brightness conditions, during the night for example. It did seem more prominent on the edge+, but its visible on the note too. All the display model note 4's and s6's did not have such an issue.
