Recently I brought iPad air 128 GB but showing 115GB why different 13GB

iPad Air 128 GB Wifi + cellular, storage capacity showing 115 GB on factory reset condition why difference 13GB,
I asked the shop staff they told me this normal for IOS and / or Preinstall app reserve storage capacity totally 13GB and this reserve will variable depend on IPad capacity model and IOS version ( more bigger capacity more reserve ) Is this true?
Example model 16 GB the storage will shown 13.3 GB different 2.7 only (my iPad [ 3rd generation ] wifi + cellular, 16GB, iOS 7.0.4, factory reset condition ) even Apple support staff in Thailand can not gave clarify my question.
Also they mention I can't return this because other function are work in order.
In my opinion this is too big reserve. Either the system reserve (iOS and pre install app ) nor the some of HDD chip are damage. Sorry if my English not good enough.
What I can do next please advice.
