Getting IPv6 to your customers is good, but they still have to use it.

If I look at my stats, I can see that the IPv4:IPv6 ratio for Netflix is 5.5:1, while for Google it's 1.1:1 and for Facebook 1.33:1 

(peak-time ratios, when traffic is mostly from residential users) . The best explanation I could get is people may use Netflix from devices that do not support IPv6, such as some/most (not-so-old) Smart TVs. There's also the issue of some brain-dead wifi APs that filter or severely limit traffic required for proper IPv6 operation (multicast comes to my mind).
