I have Spectrum at my house & while they will give me an IPv6 address it doesn't really work. The network offers up a wide range of IPv6 blocks I can choose to use. But whatever IP you use first, that is the only address you ever get traffic for. So the delegation is basically just 1 IP in practice. Also IPv6 doesn't actually work reliably. You'll notice it when browsing the web for example, there are periods of 2-3 seconds without IPv6 connectivity. This does not happen on IPv4.
