Anyone offer an explanation as to why a gloss black was used?

Presumably because it's both "black as midnight", and reflection from
the gloss paint might be mistaken for the twinkle of a star under
moonlight.
You'd have to make sure you turned the exterior lights out during
ingress and attack...but that's only tactical.

Exactly. As one who worked stealth and camoulflage technologies, I saw
things changing in the 90s. As long as there is no sun out to create
sunglint, a mirror like finish can reflect a uniform background.
Also, under the right conditions a gloss black can be "blacker" than a
matt finish. Matt
finishes quickly pick up dust and grime and are much harder to clean
than a gloss finish.
Some stealth designs do not absorb radar at all, they bounce it off in
directions that will not get back to radar site.

I've seen several sources that claimed flat black against a star background
at night could be detected. The reflections of the gloss black masked that
effect by providing star like twinkles.

If you look at the colours used during WW II you'll see a turn away from
dull matt towards gloss. The RAF had their first nightfighters in dull
black,but the rough surface of the paint decreased the topspeed some 5- 10
miles. Later they used greys as nightfighter colours.
The USN used matt colours for the tricolour scheme in early and midwar, and
later gloss blue all over.
The USAAC/USAF used to paint the planes, but in late war had a lot of planes
in natural metal finishes.
My guess is that the glossy surface gave better speed performance and the
camouflage was less nessecary in the late war where the allies had almost
total air superiority.

I THINK it was to make the plane less visible to searchlights. A gloss
surface acts more like a mirror, with the angle of reflectance equal to the
angle of incidence, so unless the light is hitting a surface perpendicular
to the beam, it will reflect it in a direction not directly back toward the
searchlight (and the searcher). A matte surface, OTOH, scatters light in all
directions, which makes it more visible under beams hitting it from other
angles. You can see the same effect sometimes at night when the road is wet
-- it's hard to see the road surface because less of the light from your
headlight is bouncing back at you.
