A bit late, but you can try this:

QApplication app(argc, argv);
qDebug() << (app.desktop()->logicalDpiX()/96.0)*100.0;

You can pass the value to the QML context, if you wish.

I don't know however how to get the default DPI value (96 on my Windows PC).

From
https://en.wikipedia.org/wiki/Dots_per_inch
this default value seems to be 72 for Mac:

Since the 1980s, the Microsoft Windows operating system has set the default display "DPI" to 96 PPI, while Apple/Macintosh computers have used a default of 72 PPI.

In any case, if your problem is answered, could you mark this question as solved?
Cheers.
