tech writer who specializes in TV screens here. You are indeed correct. With OLED, no bleed-through at all exists since there is no backlight and unless specific RGBW pixels on the screen are activated, they emit no light at all basically. On the other hand, even the absolute best consumer market LCD/LED screens leak at least some backlight glow, though in high quality models it becomes very faint due to local dimming zones and high quality light blocking.
