This certainly wasn't all we saw. There was a mix of 787s, 777s, and A350s from Aeroflot, Air China, ANA, Asiana, British Airways, China Airlines, JAL, KLM, Korean, LOT, Qatar, and SAS along with all the usual domestic operators.
If you want to see more, you can follow #dorkfest on Twitter which was actually trending in California during the event.
In the end, I stayed far later than the official 1pm end of the event. Some people headed off to the SpotLAX2021 event that evening, others just went to grab beers with friends, and some headed straight to LAX to fly back home. I think everyone who attended will agree, it was just a really fun day.
