I saw a post regarding a thin green line appearing after someone did a Bootcamp update and I also have this issue.
I want to sell my 2017 iMac and will disclose the issue but I want to know if the issue will get worse.
iMac 24″, macOS 13.0
Prepare the iMac according to this Apple document, What to do before you sell, give away, or trade in your Mac - Apple Support, and see if the line remains. It could be a failing GPU.
