Settings > Display > Navigation Bar > Background Color Options Suddenly Limited Shortly after buying my Samsung Galaxy S8, my Settings > Display > Navigation Bar screen looked like this:



I retrieved that image from Android Central.  Now, it looks like this:



Notice the significantly limited color selections in the "Background Color" section.  Also, the first image has a color picker, but the second image does not.  I'm wondering if a recent update eliminated these options.  Could any Galaxy S8 owners tell me if their settings are more similar to the first or second image?  Also, does anyone have a suggestion how I could bring back the color options from the first image?  Thank you.
I don't own a Galaxy S8 device, but it seems the recent update has removed or limited the background colours option. From this article it is certainly the case:


  Samsung is pushing out a new software update for the Galaxy S8 and
  Galaxy S8+ right now, and it looks like the company has decided to
  limit the customization options for the navigation bar. Well, at least
  when it comes to the choice of color for the navigation bar’s
  background, as there is no longer an option to choose a custom color
  from an RGB scale. In fact, Samsung has switched up the available
  background colors, and the worst of it is that you can no longer use a
  fully black navigation bar background.


Again here is the changelog of the update:



You could try other workarounds using apps to extend the range of nav colours as suggested with this app from play store. (NavBar App)
