I am not sure why you call this ignorance on your part. You buy a TV to watch and enjoy content on it. Not set google calender reminders so you remember to scan for dead pixels! You cannot forecast when a dead pixel strikes your panel. The day you run a scan, all could be well and a month later, kaboom. There isn't much you can do.
On the day you created this thread and noticed dead pixels on the section of the black bars, you did not notice dead pixels in the more pronounced areas? Was it not noticeable?
Ask LG for a good will replacement of the panel. Even if they reduce the panel cost by half, I'd pay it out of my pocket. Atleast you get a new panel, maybe another year thrown in for warranty and your mind is clear of the fact that there are no dead pixels. Besides; the cost of a new panel is likely to cost a fraction of a brand new oled.
