If you leave your PW light at level 22 (default) of the possible 24 you will never see a light dot.
Since the PW uses reflective light and not direct light like the Fire, reducing the light level is NOT necessary in low light conditions.
Light dots are only visible when the PW light is reduced to a very low level. Otherwise they would tend to blend into the high light level. The slight LED shading on the bottom of the screen is also not noticeable at the 22 light level but may get very noticeable at low light levels.
LCD screens also may have one or two defective pixels. They are not noticeable at normal viewing level but can easily be identified close in.
