I have *two* options for "no scaling", one for "display scaling" and one for "GPU scaling".

With the Dell P2720D, the "no scaling option" when set at "display scaling" does nothing, but it works when set at "GPU scaling".

With the HP 27xq, the "no scaling option" works in either case.

So, as I see it, there must be a difference between the "no scaling" between "GPU scaling" and "display scaling", or not?

Display scaling sends any resolutions listed in CRU to the monitor. The graphics driver automatically adds some common lower resolutions as scaled resolutions. That's what the "no scaling" option affects with display scaling. If you use GPU scaling, then it will affect all non-native resolutions.
