I am on the beta program and have the most recent update for version 5.4.0. I'm on a Nexus 6 on Android 6.0.1 with the July 5 security patch. I notice that when I have the color set to sepia the margins stay white. I also see the same thing on my Chromebook, which is an Acer Chromebook R11.
This is hardly a huge deal, but I thought that you'd want to know about this as I doubt that this is intended.
Blessings,
Jason
