oled black on s9 emitting light in dark

[makn99]

My s9 black oled screen(or wallpaper) emitting light in dark room. Why? 

Actually oled blacks should be pitch black and should not emit any light. But my black display screen is illuminated and emitting light in dark room. Why? Is there any problem with display ? All settings normal.
