Is Jiofi using a NATed connection even for their ipv6 address like their ipv4 address?

Jio has always been using private NATed ipv4 address AFAIK. So I brought a jiofi router to check out the ipv6 address and I see that the router has its own wan ipv6 address while the websites like test-ipv6.com shows a different one which tells that jio has even NATed their ipv6 address. Can Anyone here validate my findings? Is it even possible?
 
You may try running a whois on both ipv6 addresses. See Private network - Wikipedia for the internal ipv6 range.
 
their m2s router uses IPv6 Prefix Length /64 so effectively you can have 18446744073709551616 devices or IP addresses. But the prefix delegation is not allowed in LTE connections by default. So NAT is used. But I have still not tested after how many devices the NAT is used.
their jmr815 router uses IPv6 Prefix Length /128 so effectively you can have 1 device. additional devices would use NAT in ipv6
 
yup I have the JMR1140 which has a ipv6 prefix lenth /64. So every time I disconnect and reconnect it the ipv6 address changes just like the NATed ipv4 one. Also whois gives the same details for both i.e. property of M.A.
