Yes, very much so... here's why: In many schools the projector used in the front of the class is old and/or inadequate. Depending on the conditions, some work better with "light" applications, others better with "dark" ones, and some are so bad the only solution is a "high contrast" look (which also aids those with visual impairments -- education and the tools thereof should try to be accessible to all). Like zooming in/out, this was a bit of a favorite complaint of teachers which was very easy to fix in order to help them overcome the widespread hardware inadequacies. I guess the moral of the story is: "assume nothing". Hope this makes sense. ;-)
