Hi! Encountered exactly the same problem. I already Reset the SMC, PRam and NVRam but nothing happened. I already reset and installed fresh MacOS but still the issue is still there. As long as my MBP 2015 13” is not heated like for 10 to 20 min the green haze / tint is there or as long I the display is not closed after you open for 10 to 20 min. What did you do to solve the problem? I don’t think the problem is within the display. Any solution what did you do with your unit? Thanks.
