This is nothing that can be seen on a Macbook pro 16, for example by illuminating an iPhone led flashlight up close. Do this kind of inspection. This way, I discovered traces of dust spots that had left marks in the AR coating. In addition, a few micro scratches and I treat the Macbook like a child. My Mac is only a month old and I am devastated by the quality of the AR coating. Usually you don't only see it when you shine the light at the right angle, but that's not how it should look when paying for a premium device. In my opinion, the problem lies in the incorrectly applied AR coating or in its inadequate curing. I return the Macbook to the service and ask for a solution to the problem and replacement of the display under warranty. Hope as a longtime customer of Apple my problem will be successfully solved. Let me know about your AR shell ????
