Great update, but some minor problems on my LG V30:
The nav bar remains black regardless of the force white navbar option, probably something to do with LG's poor implementation of 18:9 compatibility, forcing the app to not use the navbar part of the screen for the app (because the navbar has some sort of black overlay that fades in, doesn't appear on all apps, seen in slow motion gif)
And Poweramp doesn't show up above my lockscreen regardless of setting. Not sure if an Oreo bug or an LG bug.
Keep up the good work!
