The point of that profile is that it is useful for looking at the map
while one is not navigating!
Seriously, I don't understand why you don't understand. One of the
things I do with OsmAnd is to look at the map (like a human looking at a
paper map) of someplace that I might go, or just want to know something
about.
So it has fewer things in sidebar, and doesn't need to assume a mode of
travel because there is no route computation.
I do wonder if the default of not having night mode is the right thing,
but that's another story.
What do you think should happen when you don't select a destination, and
are zooming out and back in someplace else?
