It doesn't need to be fake.  Light from a nearby star doing a dozen
circuits around the pocket universe will most likely appear to be
coming from a distant star, and a pretty dim one at that.  A thin
medium of interstellar gas and dust will absorb a tiny bit of the
light each pass, dimming the apparently very distant stars even more
and reradiating in longer wavelengths.

After 100k years the thermal spectrum could be pretty close to
blackbody with temperature around 15 K.  The background radiation in
our universe is closer to 3 K.
