[Spryng] Why does a «getCard» API method response not contain the «issuer_country» property?

According to the documentation, it should: https://api.spryngpayments.com/v1/#operation/getCard

But the real response looks like:

{
	"_id": "58009d04e1b39b6692edee40",
	"last_four": "3153",
	"expiry_year": 20,
	"expiry_month": 10,
	"brand": "Visa",
	"bin": "402400",
	"cvv_verified": true
}

The issuer_country property is absent.

An answer from Spryng:

I’m afraid we can only provide limited card holder information for PCI-DSS reasons.
