Is my sensor scratched?

Hi!

I have a nasty little "line" that's showing on my photos (G85 Lumix). It's on sensor (shows on all lenses). I tried cleaning it with a blower, then special liquid, yesterday I took it to a professional store for cleaning - nothing helped (not sure how "expert" they are actually...). The stain shows only above F9 or so (especially on F22), I'll post some sample images. What could it be? A scratch? Or maybe some dust that is "from the inside"? What are my options? Yes, I could just ignore it, but the thing is I was planning on selling it (already have GH5) and this could seriously affect my asking price

What if I (somehow) dissemble the whole camera and try some inner cleaning? Just thinking out loud here...

Anyway, here are the samples - the last one I zoomed in with Photoshop (sure looks like a tiny hair to me, but I guess it could also be a scratch...):
