I do not know what reference you are thinking of, but swedish
standards have become international standards before, like in low
radiation standards for computer screens, so it wouldn't surprise me
if the source is the same.
But, OTH it is not necessary to refer to any articles, it is quite
simple to explain so any sensible person understands it.
If bright white is used as background color all other colors will be
darker, so the windows operative system use less bright backgrounds to
let pictures and icons have the possibility to be both brighter and
darker. A less than bright white background will let other colors have
brightness which is impossible if the background is bright white.
Some people say: But you only have to adjust the brightness of your
monitor so the bright white is not too bright.
But then all the other colors and pictures would become very dark.
To let colors and pictures have a brightness we need to keep the
brightness of the monitor high, and hope that no programmer or web
designer is stupid enough to use bright white backgrounds, which would
have the same effekt as somebody shining a flashlight in your face.
The maximum brightness should never be used for big areas of the
screen, it should be reserved for special highlight effects or as part
of pictures and icons.
If we want to look at a picture of a summer day, with green grass and
a bright blue heaven, we need to show it against a less than bright
white background. Otherwise the bright blue sky will look dull
compared to the bright white background, as bright white means full
blast from all three colors. Nothing can be brighter than the
background in that case. All pictures and colors would look dull if we
use bright white backgrounds.

Yes, of course.
