Real-world latency is impacted by configuration and hardware (e.g. your ISP may have different routes for IPv6 that can be either better or worse, it can be handled by different routers with different performance, IPv4 traffic may be going through CGNAT, PPPoE concentrators, etc) that dwarf any theoretical differences.

Google's IPv6 stats also measure latency compared to IPv4 and in most countries IPv6 has lower latency (e.g. in the US on average you get 10ms lower latency with IPv6). When this chart was new it was mostly the other way around, with early IPv6 implementations being poor https://www.google.com/intl/en/ipv6/statistics.html#tab=per-...
