Tinting the SF Symbol of an AppEntity

As you can see in the following screenshot the „Water“ selection is an AppEnum which gets a nicely tinted SF Symbol. On the other hand, the „My Home“ is an AppEntity which also uses an SF Symbol, but doesn’t get the blue tint. Why?

Now my question is, how can I force the tint on the AppEntity as well?
I’ve defined it the following way:

var displayRepresentation: DisplayRepresentation {
    DisplayRepresentation(
        title: "\(title)",
        image: .init(systemName: "house", isTemplate: true)
    )
}

But even adding the isTemplate doesn’t work here …
