Subject: [PATCH] display: Update night light scale to new blackbody
 calculation

g-s-d was changed to use a better black body temperature calculation.
This strongly affects the effect of the color temperature (the default
is changed from 4000K to 2700K). Update the scale to represent a similar
range to default even if the distribution on the scale is quite
different.
