U2715H, different coatings, #2

I have a similar situation but the issue doesn't stop there. I have two A01 U2715H monitors and one A08 U2715H monitor. The two A01's that I bought in 2015 were manufactured in December 2014 while the one A08 that I bought two days ago (12/9/2019), was manufactured in July 2018. The A08 has noticeably more matte coating, and this matte coating has a heavy greenish tint that was making all colors appear wonky and not matching to my A01's. Backgrounds that should be white were green-white. The only way I could even closely match the A08 to the others was to set custom color setting in monitor settings and reduce the R to 94 and G to 88 while keeping B at 100; I also had to go into Nvidia control panel and adjust the desktop color settings for the A08 by reducing digital vibrance (default is 50% and I reduced to 45%). Seriously wondering why I paid extra for this Ultrasharp if the colors are going to look quite off from what they should be and not even match my other monitors that are the same model number.
