Will I benefit if I am not really a bluegrass player?

Yes. The skills are the same, the notes are the same, the techniques are the same, it just the style and songs that are bluegrass. You will learn skills that cross over to all sorts of music.  Many of the players play other style of music as well, but at a bluegrass festival, well, the focus is on umm.. bluegrass.
