I noticed that the ipaddr filter seems to compress IPv6 addresses.  
For example I feed a list to ipaddr that contains (among other things)

To answer my own question, it seems there is: ipv6form.  
The docs are mangled though:  
[https://docs.ansible.com/ansible/latest/collections/ansible/utils/ipv6form\_filter.html](https://docs.ansible.com/ansible/latest/collections/ansible/utils/ipv6form_filter.html)  
I was able to get what I need by reading the source.
