KDE / Qt doesn't default to the value actually reported by the hardware
either, because X doesn't report the size of the monitor as the
DisplaySize. It just generates a DisplaySize that will result in a DPI
of 96. So in almost all cases KDE / Qt carefully calculate a value that
X has set up to basically always produce 96 in the first place.

R12.c#n787

The only case where this doesn't hold is if X configuration contains a
DisplaySize (manually added by the user or by the distro or some config
tool or something), or if the -dpi parameter is passed to X (in which
case X generates a DisplaySize that matches the requested DPI).
