2018 13" MBP, screen takes on a blue tint

[ascender]

I originally thought this was my external monitor playing up, but it looks like its an issue with the laptop. Any ideas what I could try other than the usual resets and a complete reinstall?

I'll be working and the screen will suddenly just take on a blue tint, as if someone's added a blue filter to the front of it. It happens randomly, doesn't seem to last long and doesn't matter what app I'm using at the time or how long I've been on the laptop for.

I've taken screenshots when it happens and when it reverts, but I can't seem to see any difference in them which is weird.

Any ideas?!?

It seems that getting a Genius Bar appointment is easier said than done at the moment. Does anybody know what time the appointments get made available? I've tried checking last thing at night and first thing in the morning but the next week's slots are all taken...

Finally got a Genius Bar appointment. Graphics card is failing, so machine needs a new logic board which has now been ordered. There's a backlog of repairs unfortunately so I just need to hang on to the laptop in the meantime and hope the problem doesn't get any worse.
