Good. The monitor reports 331 x 207 mm (which you should be able to verify with a ruler). If that is correct, the dpi should be 1280/33.1*2.54 = 98.2 and 800/20.7*2.54 = 98.2. It seems like it uses 96x96 anyway:
(==) intel(0): DPI set to (96, 96)
Then this is back calculated to a "real" size of
1280/96*2.54 = 33.8 cm and 800/96*2.54 = 21.2 cm.
I will close the bug since your original issue has gone away, but I still wonder where the 96x96 is coming from. We used to force it in Gnome earlier, but I think not anymore.
