iPad screen colours washed out

Hello,

The colours on my iPad’s screen appear washed out. All the colours work - but everything appears bleached. Sometimes the issue fixes itself and the screen goes back to normal, but after a minute or so of use it goes back to washed out colours.

I’ve attached a couple of photos to show what’s happening - a picture of the screen and the original photo to compare it against.

Not sure what’s causing it but fairly sure it’s a hardware issue as I did a reset all settings and complete DFU restore to hopefully rule out any software issues.

Any ideas for what’s going on?
