I've no idea whether it works, but they misidentified many apps I don't have installed (Postman, Express VPN, Notion, Figma, Hotspot Shield)
It does do the popup for VSCode asking if I want to open links there, which I do have installed.

I.e. there are some schemas which lets say XCode handles but which also some other program handles.
I don't think you understood the core of the issue: it's not about identifying which applications you have installed, it's about always getting the same result for the same user. If all your browsers serve the same results, you are trackable, no matter if those results are good or not.
