I wouldn't describe that as persistence being a problem, since obviously the LCD can be illuminated for arbitrarily short periods of time. The response time penalty applies regardless of whether you're trying to run the LCD in a low-persistence mode. An OLED's response time advantage over LCDs is across-the-board and completely orthogonal to persistence (where some kinds of backlights could enable LCDs to strobe even faster than OLEDs), and the impact of 5ms extra lag for VR applications will be about the same with or without strobing.
