IPAD Pro 12.9 inch white spot patch spreading

This appears to be a somewhat isolated screen issue with the 2017 iPad Pro models.

And, once again, only limited to a very small percentage of 10.5 inch iPad Pro models.

So, how will this help you?

As I continue to state, this is not a common issue/defect and appears to only affect a very, VERY small minority of 10.5 inch screen iPad Pro users.

We aren't even seeing this issue in these official Apple iPad support communities and I monitor these communities every single day.

How does this help you?

We can't tell you what is causing this. We also can't tell you how to fix it. I don't see many posts from others with the same issue. You're only choice if it bothers you is to take to your Apple Store Genius Bar for evaluation and options. Apple does not fix or replace iPad screens. They offer out of warranty replacement for about 60% of the price of the unit when it was new.

Sorry and good luck.

This is not a normal manufacturing defect that we see in these iPad support communities.

I have the same nearly 4-year old 12.9 inch screen iPad Pro and I do not have this issue.

There is no real way to know, for sure, if this is Apple's fault or something just happened with your iPad hardware over time from use.

So, your choices now are very limited.

Pay for a 40% off discount for a replacement iPad Pro of the same year and model as yours or live with this issue.

OR

Purchase another new iPad or a discounted, refurbished iPad from Apple's Website.

Newer iPads now support the 1st gen Apple Pencil, now, so there are more iPad/Apple Pencil options, now, in Apple’s iPad lineup.

Your screen issue is an very rare and isolated issue.

So Sorry & Best of Luck to You!

Here's the thing. You found a thread with 50 posts, some are repeat comments, so in all honesty, less than 50 people. This is statistically insignificant when you consider Apple sold literally millions of the same iPad.

The reality is the only voice which matters in this, is Apple's voice. You need to schedule an appointment at the Genius Bar and see what if anything, they will or won't do for you. If I were you, mentioning a thread in another forum, which is not an Apple Forum, most definitely won't help you or be in your best interest.

There is still absolutely nothing anyone here can do for you. And the assertion that this is not a common issue is still fact. I'm sorry it's happened to you, but the vast majority don't have this issue.

And this helps you how?
