Turns out it was the screen, moving the projector physically the bands did not move their position on the screen.
Projector people (awesome support) called da-lite. I don't remember this from day 1, I only noticed it recently and I have had it for 3 years. Da-lite said it could be a defect that appeared over time but out of warranty, so they offered 25% off a new screen.
ALSO, in my frustration I got ballsy and blew the dust blobs out. It was actually pretty easy and I got all of them out except for one which isn't too bad.
Anyways, I am not sure it is bad enough that I will buy a new screen, we'll see. I actually feel a lot better knowing it is not the panels and probably won't get much worse than where it is.
