Reading the article that OP’s article linked to, two points:
It seems that other manufacturers are also running into this problem on phones with AMOLED displays too.
It sounds like some vendors may be telling their service centers to replace the issue if a user shows up with it, but not announcing the fact publicly:
Some OEMs like Samsung, Apple, and OnePlus have advised their service centers and support channels to assist users affected by green line issues and repair devices for free, even outside the warranty period.
However, such advisories have not been issued by way of announcements in the public domain. Instead, they are offered as solutions at the customer support and service center level on a case-by-case basis.
