Does anywhere actually show much "guilt of having displaced native inhabitants"?
It's just a brief statement along the lines of "We acknowledge that this event is taking place on the unceded territory of (list of indigenous tribes who inhabited the specific region)"
There are debates about its merits as an actual tool of reconciliation, but I don't think it's possible to argue that it isn't an expression of guilt by the cultural majority.
"The Britons they first drove out, the Picts they utterly destroyed, and, even though very often assailed by the Norwegians, the Danes and the English, they took possession of that home with many victories and untold efforts"
Not very apologetic!
It's a rabbit hole.
