AppleCare for the Macs is definitely worth it. They even replaced the display on my MBP after 5 years when I called (that seems to be the key is to call someone at Apple directly). This was a part they should've recalled, but anyway I wouldn't have gotten a new display without AppleCare.
There was a display replacement program for 2012-2015 MBP13s, due to the staingate. Though I recall that it was for 4 years since date of purchase, or so.
Yep it was related to that, even though AppleCare ended up replacing my screen after 6 years (not 5 like I initially remembered). It was an unexpected bonus and I’m still quite happy about it. But the key was to call AppleCare directly and not go to the geniuses.
I wonder if there will be one for 2019 MacBook Pros. The repair shop said the replacement display was also faulty, so they had to order a replacement replacement.
