Default Taiwan M8x

Hi guys,
I have an imported 32gb Taiwanese M8x, FA serial.
It unlocked, s-off's and has a GPE rom running. Its blazing and it works on all Telstra frequencies.
My question is what is different about the M8x vs the regular M8?
Its it an LTE-A version?

Oh and I got it because the two Chinese made versions has terrible screens.
