Retina Anti-Glare Coating Restoration

If your specific individual MacBook Pro was purchased within 4 years (according to Apple) you would qualify for a free replacement. So if it's a Late 2016 model or newer it's definitely within 4 years. You should contact them immediately if there's any doubt and ask them if you qualify for the 4-year anti-reflective coating program. It they don't give you a definite answer you'll need to get it escalated. And be sure to get a case number.

You can't strictly go by the year/model number because even if you have a 2015 model it could still be within 4 years if it was an old model when purchased, but done Sept. 2016 (or later).

If it's past the 4-year mark then your options would be to use it as is, pay out of pocket for a new display, use an external monitor, or remove the anti-reflective coating entirely to get a perfect, if a bit high-glossy display.

There are a number of Youtube videos explaining what you can use to easily remove all the coating. The main danger is dripping whatever liquid you use into the MacBook or under the bezel and shorting out the screen. Personally I would be absolutely diligent about how you do it and not allow the tiniest drop to get anywhere next to the edge and wait 48 hours for whatever you "didn't" get there to fully dry before turning on.
