For me at least the vast majority of the data is being downloaded from various servers under bootstrap.libp2p.io or preload.ipfs.io. These are clearly dedicated servers not true peers.

The contact info for these servers appears to be retrieved via the DNS rather than the DHT. This isn't surprising because browser clients can't participate in the DHT, but the DHT is currently one of the biggest weak points of IPFS. IPFS's DHT is so chatty that it consumes over a megabit of throughput just to maintain an idle node. Lookups are excruciatingly slow and often fail completely.

Sorta, a peer can advertise dns addresses, and the browser can participate in the dht as a client. The example above uses webrtc-star for browser to browser discovery.
