It also comes up with very expensive OLED monitors, which do usually have true RGB or WRGB pixels, but their subpixels are usually not arranged in the standard horizontal RGB stripe which breaks most implementations of subpixel font rendering. With a sufficiently high pixel density it doesn't matter, but with the ~108ppi of a 27" 1440p OLED monitor the text rendering can be quite visibly worse than a 27" 1440p LCD.
