Is this an actual nebula or CGI? I'm thinking of putting a large wall paper with an astronomical motive on a wall. I found quite a number of wall papers by various vendors, but most of them are obviously computer generated images, which is a no-go. It must be an image of an astronomical object, a nebula or a galaxy. (There's also a size requirement, not under 236 x 370 cm, so please do not suggest I use a printed image fitting a common frame format).

Now I found this wall paper. To my eyes it does not obviously look like CGI. But there are no diffraction artifacts visible for the bright stars; perfect circles it seems.

Can anyone identify the object?
This appears to be one of Sergii Tsololo's more convincing efforts in the synthetic "space" image genre.
It is listed on various stock photo sites as
"Blue and purple space galaxy,"
or with added 4-way spikes,
"Blue space starfield with flares."
A real astrophoto would identify the subject and not be tagged "abstract" or "fantasy."

To check it another way, I submitted the image to
Astrometry.net,
whose plate solver failed to match the field within their 10 minute time limit.
When I submitted an amateur photo of the
Trifid Nebula
as a control, Astrometry.net found a solution in less than 1 second.
