iPhone XS Rear Camera Blue / Purple Tint

I seem to be having an issue with my rear facing camera where upon taking a photo ( especially in low light) colours that should be white appear a blueish or purple tint. Other colours seem to come out just fine. Please see example Where tv and reflection go this crazy colour. I’ve only had the phone a couple of weeks and it’s definitly an Issue in terms of photo quality. I’ve tried re- setting the phone etc but the problem doesn’t go away - do I need a replacement?!
