I'm sorry to hear about your issue but only your Local support can answer that question.
Pretty much the same answer as your previous post in 2014
The tellow tint, as reported for other devices, could be due to the glue used in construction. If it is so, it could be gone away in several weeks, but it is a certainty.
You can wait and see the situation in the weeks or manage the white balance, but remeber that Sony doesn't give RGB values to correct the white point, so you must go "at eye".
