Has anyone ever seen any white led 7 segment displays?

Do they exist?

Blue LED certainly exists (I reviewed Lite-On LTS-5501AB here in this
newsgroup several years ago) but I've yet to see white, even though
the semiconductor technology should be similar.

Numitrons have nearly-white segments, especially at 7V, but the
filaments tend to burn out quick if you run them there :-).

I've also seen 7-segment displays built with 4-foot flourescent tubes!
