Is it okay to put a screen protector onto a MacBook Pro 13 inch Retina's display?

There is a lot of ambiguity with this question of putting a screen protector onto a MacBook Pro, I currently have a 2016 model and it is pristine condition however my previous model suffered to the "staingate" incident and had to be replaced, due to the value of this product and afraid of this happening again plus the annoyance to my OCD of tiny dust scrapes is it acceptable to put a screen protector onto a retina display.

The reason why I ask is surrounding the interpretation that the Retina display itself has a "Spray on" protective anti glare cover and therefore putting a screen protector will damage this upon removal in the future.

What is the right answer can you or can you not ?
