No, I promise, Windows Update does GAF and it is system aware. There are often times when updates will be delayed to certain hardware configurations due to said configurations experiencing blocking bugs, while sometimes entire processor families will be ineligible to receive an update (meaning you won't be offered the update through WU).
This happened with early Intel Atom processors around the time of the Creators Update in Windows 10. I had a Samsung ATIV Smart PC 500T that
wouldn't get offered Creators Update through normal means or Insider rings, and wouldn't install if I tried to force the issue by downloading the update manually.
Windows Insider is just one of many flighting rings in Windows Update that
largely ignores these checks, but that's not to say it always will. Whenever Windows 11 moves from Build 22000 to the next major build, there's a solid possibility some machines won't be offered it without switching to an Insider ring. And even then, switching to an Insider ring might not work a la Creators Update on early Atom.
