I'd say the inverse is true: OLEDs are the best in low light, as they generally dim well and black means zero illumination of the pixel. Author is ill-informed. Also, OLED burn-in is a non-issue with current displays in any normal situation (e.g. not a kiosk or arcade or other sort of always-on static dashboard).

Like the taskbar, dock, menu bar, etc.?
No, those are generally not always-on in normal use. People let screens shut off, open up fullscreen apps, etc. Most OLED firmwares also have subtle pixel shifting and pixel refresh on shutdown routines, as well as very conservative brightness settings. OLEDs in normal use are actually less susceptible to color shift deterioration than LCDs in normal use.
