HDRP is new to me and I'm attempting to set up this space scene so a pitch black skybox. I tried just setting up quickly a pitch black gradient sky, and it's caused this EXTREMELY overexposed scene where the only fix I've found is maxing out the minimum exposure, which of course is just a hacky workaround. Maybe not helped that the light I attempted to build is causing light leak through the mesh because I guess it doesn't have a backface maybe? So it's sun drenched over exposed interiors too 😛

I'd check the frame debugger first. See where it originates from.

That's expected imho.
You have very high intensity lit object over a pitch black background. The overall screen intensity is low because of the background so auto-exposition is quitte low.
What you see if the effect of the bloom post process that bleeds a lot of the hight intensity pixels.
Either force the exposure to fixed value or use exposure compensation in the auto exposure.
You can also disable/reduce the bloom effect.
