Assuming that the 'wrap around' has no refraction in it, the light
leaving a star should arrive back at that star. So to observers on a
planet it would be like there was a dim star just like their primary  in
exactly the opposite direction. For the star itself, aside from the
small amount of energy blocked by planets, rocks, dust, etc., the whole
sky would be glowing with its own light returning.

What it would do to stellar life having almost all the emitted energy
returned to a star, I do not know.
