Any consumer ISP worth using should themselves be a tier 2 network, which means that for full global routability, yes - they take transit from peering with at least one tier 1 provider, but the bulk of their transit will come via peering at neutral internet exchanges - paying just for per-port costs and potentially membership fees. They are also then free to peer directly with Netflix, who have an open peering policy: https://openconnect.netflix.com/en/peering-locations/ https://openconnect.netflix.com/en/peering-locations/ If you're pushing enough traffic, Netflix will also send you an Open Connect caching appliance for free: https://openconnect.netflix.com/en/appliances-overview/ https://openconnect.netflix.com/en/appliances-overview/
