Is NS really active? I mean if I recall it default to use automatic NS during night time but turns off during day.This is my 15PM at 100% with TT and NS (I always keep them turned on).
Can you check it respond if you move NS slider to fully right and image get warm?
Can you take of photo then?
I'd give my kidney for a panel like that.It's ok to me. There sure are better panels out there, but I'll settle with this.
Not sure if this is some region thing but in my area I have not had much luck getting perfect panel not even ordering directly from Apple as I did with 15 PM and my previous 12 Pro.
