Android's header bar color in running apps carousel view



I observe some inconsistencies between the header/status bars when I enter the running apps carousel (by taping the left android hardware button).

Here is a screenshot of my header and status bars:

And here what it renders when going to the running apps carousel:

As you can notice, the window bar takes a light blue color (which seems to be the ionic blue, right ?).

Does anyone have any clue on how to change that color ?
Is this specific to Nougat (on Samsung S7) ?

Thanks for your help.
