Even if you could add a contrast control to the SE/Plus, it wouldn't
make the letters darker.  The screen is already running at maximum
contrast.  When you turn the brightness down, the letters don't "become
gray also" -- they stay the same, but your eye interprets them as less
black in comparison to the now-dimmed pixels.

Try a polarizing or mesh glare-reduction filter in front of the Mac screen.
Or turn down the room lights.  Either solution will cut the reflection
of ambient light from the gray surface of the screen where the pixels
aren't turned on.  (Both are easily applied and potentially removable.)
