Update - I received my new 14" MBP yesterday... the screen on this is fantastic, regarding the coating issue the other one had. Here are comparison pictures...
Light diffusion -
Old laptop - poor diffusion, very hard on the eyes. Using the laptop with a light source behind me was hell.
New laptop - excellent light diffusion... basically the way these laptops should come. No issues here.
Here's another comparison pic that MIGHT be hard for some people to see. But I can see it clearly... if you compare between old and new laptops... you can see the depth of field effect I previously mentioned, making it extremely hard to read or use the screen, with my eyes constantly trying to focus. Center of the screen was brightly lit. Sides of the screen were darker... caused by poorly applied coating, IMO.
Old - if you look at the wallpaper, you'll notice the left and right side of the sky being darker.
New - evenly lit screen... the sky is evenly lit, having a properly applied coating allows the miniLED's to light the screen evenly. Left and right sides of the sky are evenly lit.
Unfortunately I'm probably not keeping this one either though... the edges of the screen coating are damaged it seems. With spots visible and a scratch into the coating on the edge. There also seems to be a dead pixel or dirt right in the center of the screen.
