Are you wanting specifically a anti glare screen protector or just any screen protector?
On my 512 oled I used the jsaux brand hd clarity variant screen protector and when putting it on I can barely tell its there. It came with two with the first one being put on my lcd model.
They also have a anti glare and anti blue light but I never used those so dont know how they will make the screen look

Sent in my original deck to have the right bumper repaired. Upon them receiving it it got shipped back to me in about a week.
