Bingowings:

it's a NASA painting of what an accretion disk might look like and not CGI at all

That doesn't necessarily make sense.

What doesn't make sense? The background is a physical painting commissioned by NASA to illustrate what an accretion disk might look like which I put into the space to replace the original spiral and not CGI.

As I said the colours may give it the impression of being CGI because early CG depictions of space (like B5) were very colourful.
