Your belief is rubbish. I received a brand new P2XL from Google on the Monday following Easter (April 2d, 2018). Completely and properly sealed, and with the inner plastic wrap totally untouched. I just checked the IMEI and the manufacture date is November 18, 2017. So Google does still have new stock dating from November for purchase, because I received one.
I understand everyone's concern regarding the blue tint. I myself see the blue tint on my screen, but I found it to not be troublesome enough to return the device. After all, my Nexus 6 using a Samsung panel exhibits the same tinting to the same degree when holding the screen at an angle to sight. My Galaxy S4 prior to that with (at the time) Samsung's best AMOLED screen also exhibits the same tinting, though in that case the tinting is more pronounced being an older display. I simply never noticed it until people like yourself brought it up.
Issues with ambient light sensors, partial yellow tints, and other similar defects are one thing, and for those I would exchange devices. But to exchange devices because of blue tinting at odd angles, a side effect with all OLED displays regardless of who makes them? I believe that to be a waste of time, but then again I also believe this "tintgate" controversy is simply overblown.
