No upgrades?

I have an unrooted SM-N910G purchased directly from Samsung in Singapore

The last update I received was 5.0.1

N910GDTU1BOC7
3.10.40-5042088
Build LRX22C_N910GDTU1BOF1

I heard that newer versions would be rolled-out, but whenever i have the system check,
it tells me this is the last upgrade.

can someone tell me whether I am doing something wrong?
