is it possible to display the value in filter title outside MyVideoNav.xml ?

I mean when I go out of "MyVideoNav.xml" I want to display the filter title value on the header for example.

I make some test from this info :
https://kodi.wiki/view/List_of_Built_In_...deoNav.xml

Read this thread but it is a bit dated :

The best I can is to displayed an info if there a filter or not with booleen :
 

Container.Filtered

Any suggestion or answer are welcome
Thanks
