Does the Sony Xperia Z5 have built-in air DTV (DVB-T) capabilities?

The Sony Xperia Z5 is available in many variants. One such variant, NTT DoCoMo Sony Xperia Z5 S)-01H allows you to watch air DTV (DVB-T) using the TV/Mobacas antenna cable SO02.
Unfortunately, this variant is not available outside Japan.
I have beeen told that all Sony Xperia Z5 models/varants can be used to watch air DTV but I am not sure this is true.
Has anyone tried to down the NTT Docomo TV Box app, available on Google Play:
to see whether there is a built-in TV chip in all Sony Xperia Z5 models/variants?
