Different bios version includes different pn. Submitted change fixed my inverted screen after reboot.
I've stepped back to the bios version 5.11 28.04.2016 in an attempt to troubleshoot Windows Hello locking the sign
in on reboot. The screen again rotated, but 90 degrees to the right. I created a new hwdb line to resolve that issue. The bios version changes the dmi string including the svn and pn.
