With ipv6 you can match IPs realistically to a single household across multiple sites.
Access porn.com from 12.34.56.78 and you are one of dozens of households. Just because Bob Bobson who logged into Netflix is on the same IP it doesn’t mean that house was on porn.com.
Access from 2100:1234:5678:abcd:: and you are accessing from one specific household, even if the lower 64 bits differ. You’ll likely keep the same ip for longer than in cgnat anyway (and by design you keep it until your isp changes)

Untill you can access ISP logs you can never tell anything more than 'this client accessed from $ISP from, probably, maybe, $CITY'
With Cag nat yes
