No. it's the backlight leaking if too high. The polarisers are not perfect. A normal LCD or QLED screen is fully illuminated behind the "black" pixels. It's mitigated (as are any internal reflections) if the matt top layer also has a grey tint. This also increases contrast and was done even 70 years ago on some TV sets. Reflections are attenuated twice and the display light (CRT, Plasma, EL, LCD, OLED, LED, VFD, QLED etc) is attenuated once. The trick of a tint to the top layer can't be done on eink or mirasol or any kind of reflective display technology (including simple LCDs with a mirror and no backlight).
