Random artifacts on iPad Pro 10.5's screen

[Sebaall]

Has anyone else encountered weird white artifacts showing on iPad Pro 10.5's screen? They appear randomly on my screen while displaying dark content, almost always on the bottom of the screen (home button edge). They look like randomly scattered white pixels. I managed to catch them on video (on video they appeared as line near the edge of the screen, but normally they appear on larger area of screen) - https://gfycat.com/GlossySlimyIvorygull. I'm not sure if it's hardware problem or software one (I have iOS11 beta installed from the beginning and haven't yet restored back to iOS10 to check it). Has anyone encountered those on iPad Pro 10.5 with iOS 10 or other device with iOS 11?

UPDATE:
I restored iPad back to iOS 10.3.2 and the problem persists. So I am probably going to return it as I am still on 2 week return period. That's my 3rd iPad Pro 10.5 - I got one with really yellow bottom of the screen, then one with dead pixel and then this one...

Hi all! I bought my 1st iPad Pro 10.5 last Thursday and it also has the same problem (moving scattered white lines) like what he’s mentioned above. I exchanged it today because of that issue plus severe backlight bleeding on the upper left side and some yellowing on the bottom screen. I’m finally happy getting a perfect screen on this second iPad Pro (coming from 4 exchanges of the 6th gen iPad eventually returning the last one), however, I found 2 dead pixels! Would this be a problem long term or should I go through that hassle of exchanging it again? Also, does Best Buy have a limit on returning/exchanging defective items?
