Light bleed on HP Zbook X2

Hi

I bought a customized HP Zbook X2 like 1 year and a half ago, but some months ago, while I was browsing a webpage with a white background, I noticed that something on the screen was displayed yellow.

This problem is more visible on dark backgrounds, and it's quite annoying. I contacted HP support and they changed the screen 2 times, but it doesn't improve. In fact, I'll say that it got worse.

What can I do? It's evident that changing the screen again is not going to fix it, and it's a waste of time and resources.

I've attached 2 photos of the problem (I'll update the thread with more up-to-date photos later)

 

@fuji : Out of curiosity, what is your brightness set to (or what was the brightness when you took the two images)?
