Nice post, Hawk.
From what I've read about the cost, Samsung, Hisense, TCL, etc. all have plenty of margin to drop qdot TV pricing. Most of the numbers I've seen are saying that the cost to add a sheet of qdot film to a existing LCD manufacturing line is only about $100 per 65" TV.
The display manufacturers have their new TVs significantly priced over their other 4k TVs. LG will just end up pushing the non-OLED competition into reducing their profit margins. Who knows, by the time LG gets OLED costs under control someone might perfect QLED and it will compete directly with OLED, hopefully with equivalent or better performance and better price.
