Inspiron 15 7560 LCD Replacement Concern

Hi, 

I have recently got my LCD replaced under warranty, I have been using this laptop for almost 4 years now. 

The previous LCD had bright white color and the current replaced LCD has a dull white color. 

It is very hard for me to adjust my eyes with this new off white color. 

My Question is that if this is an issue with the replaced LCD or is it normal to have LCD throw off-white color instead of bright white color. 

Is there a way I can recalibrate only the white color for the screen? 

Any suggestion would be appreciated.
