9370 vs 9380 (yellow tint)

Hi all,

I have two dell xps 13 laptops here. 9370 and 9380 both UHD touch. 9380 seems to have yellow tint display (esp. if you are not sitting in front of them) compared to 9370 and backlight seems to be reduced. Please see comparison photo . Is this display issue or there are differences between displays for this models? According to specs displays should be the same for both.

Thanks
