There was a replacement program for a bit, so there was a possibility to change the screen, though after some time changed screens are peeling off too.
I know even an anecdote where almost brand new 2016 rmbp after working outside, had a spots of peeled off coating, because apparently light dust have scratched it. Thankfully Apple replaced the screen.
Also not correlated to putting pressure on the lid with it closed, I've lugged mine around in a backpack full of stuff for years and have no peeling issues.
Then they changed so the default was glossy and anti-glare was more expensive (but, IIRC, had more resolution).
The retina display is the first one I remember where the anti-glare option was not available.
I picked up a grey market anti-glare display assembly (upper clamshell) for my 2011 model back in 2012 or so and it dutifully served another few years.
