In general, qtdiag will tell you. However, this decision may be 
different for each application, and it's not uncommon to find 
applications that override the system default.

You can enable sufficiently verbose logging for a given application to 
find out what's going on, e.g. via

QT_LOGGING_RULES="qt.qpa.*.debug=true" yourApp

HTH,
