The image doesn’t show the issue well, but my 2014 rMBP is getting worse in terms of the failing AG coating on the panel :(. I looked into the cost of replacement displays years ago and that totaled out the notebook as-is. These days the threshold is a lose lose proposition now that M1 is out, and it has resulted in a market flooded with ‘14 and ‘15 rMBPs like mine. If the chance was there, then that window left when Apple Silicon killed Intel and caused mass market saturation of whole systems. Failing a economical display replacement due to the limited official OS stopping at Big Sur, market saturation due to supply and demand and raw age, is there a way to stabilize the failing AG coating so it no longer spreads and stays where it is at? Maybe it’s time for me to call uncle to this specific rMBP and admit while I didn’t make it to the finish line, I got there 95% of the way. At is point if I cannot stabilize it I’m going to live with it and get a 2015 DG, or buy one of those new 16” M1 Max/64GB/1TB machines… Yes the M1 isn’t exactly a 10/10 yet, but it checks all of the major boxes I want to see, on the CTO side — tons of RAM, a large default SSD and it supports the P3 color spec on the internal display (Apple P3) out of the box. I didn’t look super close at the Best Buy demo 16”, but I know those are built around P3 and it was built for it. I even tried P3 on my 2014 — the Epson sRGB 1.8 color profile is a better match with sRGB IEC61966-2.1 being very close.
Hi My 2014 15inch hast the exact same problem and I looked into it and you can get this gel stuff which apparently removes the AG coating and leaves your display really shiny but after you have removed the coating I’m pretty sure you could just put a screen protector with a anti glare coating on it which should fix the issue Hope this is some use to you Any questions please ask Thanks
