iPhone 12 Pro Max display looks yellow

My iPhone 12 pro Max was heating around the volume rocker button while I was using the camera. So i visited the nearest apple store for comparison. There was a complete surprise waiting for me there. I was absolutely shocked to find my iPhone display having a yellow hue to it when compared with other display models in apple store.

So, i contacted apple support from the store itself. They took my iPhone screen on remote & suggested few manual settings to correct the issue. Unfortunately it was not fruitful. The associate asked me to update my software patch & check if the problem persists. However, as a customer I am displeased to encounter such an issue after buying the top line-up apple product. !!

Please address the issue & advise if i can exchange my device. Since it’s been only a week after i bought the iPhone 12 Pro Max.
