Yes, it's from Insomniac GDC talk about the Spider-man technical postmortem. They talk about streaming the low-quality MIPS first and the MIPS0 load fast enough that they load before you turn and see the shops. I guess that's why Cerny chose to show Spider-man for the SSD demonstration, it's already built really well for streaming:
(I don't have the exact time-stamp but the whole talk is extremely interesting
)
They have the initial 20MB of the tile streaming in before you reach it but when you enter the tile, they are still streaming 12MB per second of data around you. Obviously it's cruder than what the PS5 and XSX can do and also results in some pop-in, but the idea is similar, having the low-quality assets in memory while the MIPS0 load and if the fail to load in time, no big deal, you get a tiny pop in for a fraction of a second.
edit:
I've timestamped the video.
