The Garmin screens have a partially-mirrored surface behind the display (they are called "transreflective"). The idea is to use the ambient light (sunliight) to illuminate the display instead of needing a backlight.
Yes, given that it's a mirror, the angle of incidence and the angle or reflectance matters.
The problem with backlights is they aren't powerful enough to compete with the sun. (This is why phones don't work as well as cycle computers.)
The compromise of transreflective displays is that the colors are a bit dull compared to what people are used to for phones.

The brightness setting is for the backlight setting. For normal use in daylight, you don't use the backlight (all the time).
