I have two dozen iPad Pro 12.9" all with screens turning deep yellow - Apple Help!

I have over two dozen iPad pro 12.9" devices wall mounted in retail stores used as kiosks for customers. We run an in-house app that allows customers to browse inventory. The ipads have been installed and in use for just over 1 year and all of them have significant yellow discoloration in the screens.

The two pictures attached 1.) a screenshot is taken of the home screen from the ipad pro 2.) a picture of the same ipad pro taken from my iphone. You can see how deep yellow the screen is.

When I contact Apple they say it's out of warranty and there is no further information available. I see several people discussing the same problem on the forums w/ no input from Apple but clearly, this is a defect with the iPad pro product and they should address it. I need to replace these devices but I don't want to spend more money on a product that is going to turn yellow in a year.
