Yes it appears so. But there seems to be a few requirements [0].
Also bear in mind a /64 is more than 18 quintillion addresses so it might be a bit more expensive. And it appears they only offer /48's to individual businesses if they meet the criteria but that is still billions of IPs.
/64 is just normal allocation that every home connection should get. (/48 in this notation is bigger)
Given these amounts of addresses subnetting philosophy is quite different from IPv4.
I completely forgot about that difference with IPV6 and IPV4. You are right. There are still many thousands if not millions of addresses available to those who want them. And compared to IPV4 everyone on the planet could have a /64.
Here is a decently comprehensive serverfault post[0] on the subject of IPV6 subnetting.
