.... what does it matter. Don't buy into all this screen model nonsense. Over the years there have been issues with every make and model number of retina screen that apple has used.
If yours is good, it is good just enjoy it.
If it isn't good return it and get a different one. The model number and make will have no impact on this and is superfluous information.
Check out the thread on this site regarding screen types on the 13" 2015 rMBP. All screens can have problems, some more prone to have issues than others though.
You can either try to calibrate it out or take it back, again the make and model number mean nothing here both samsung and LG screens have come up warm or yellow tinted for many people.
