If you know that your monitor is a 3rd-generation QD-OLED panel, then you probably know that text rendering was the main complaint about earlier generations of QD-OLED, and there are probably still more of those in the wild than ones as recent as yours.
This is also a very valid point. The improvement in text clarity on this panel was one of the key reasons why I decided to pull the trigger on this $1,000 monitor, while I had passed on previous models.
