Doing this on GrapheneOS's built in Vanadium browser, I am concerned to see that the ID remains the same if I move to incognito tabs, or even a private space. Or perhaps Vanadium is doing such a magnificent job of reporting generic info that this ID would be the same for anyone using Vanadium on my model of Pixel, but I don't think so, since the site says it has a "clean read" on all the info it takes. I really do not know. Curious what other Graphene/Vanadium users are seeing.
