I have also been in the industry for over 20 years, I have never seen this type of issue with dead pixels. I sell hundreds of phones each month on many different manufacturers and this I have seen once or twice. So sadly I think your having bad luck
I have a v30 for my work phone (note 8 for personal) I had the g6 before and my 30 is much better than the 6. Better pics, better looking screen.. Etc... Just better.
Usually this is from pending updates or the storage is almost all full. Always remember to restart your device once a week to keep battery in good shape, otherwise you get to the point where the battery is dead
