Is this dust behind my iMac's screen?

I've noticed this issue for several months but kind of ignored it, until I read the article about the class action lawsuit. It's a 2015 4K iMac that I've had for three years. It's hard to capture but it's quite visible to my own eyes.

Tip: if you can't see it, it helps to make the image smaller or view it from a distance.

Given it’s position, I’d say most likely.
