The image on the Black Holes page is scientifically inaccurate. It just shows a slightly fuzzy black sphere against a generic starry background. A realistic version would show the background being distorted by gravitational lensing caused by the black hole's gravity bending the light that passes near it, and the black hole's edges should be sharp. Maybe there could be an accretion disk too.

That does sound like an important issue to fix, so anything that is more accurate you can find would be good to replace the image with.
I would like to propose replacing the current image with this one , which I got from this article https://io9.gizmodo.com/the-truth-behind-interstellars-scientifically-accurate-1686120318 (which I found worth reading).
