Huzzah-- the only command I've ran so far was to turn Dolby Vision off
am start -n com.droidlogic.tv.settings/com.droidlogic.tv.settings.display.dolbyvision.DolbyVisionSettingActivity

I have the system set for HDR10, I'm no longer getting forced HDR outside of apps but I did get HDR with a Netflix title. This is great.

edit: rebooted and Dolby Vision is re-enabled again. Too bad...

I was wondering if the adb settings would survive a reboot. Hopefully a firmware update will expose these settings -- at least it doesn't need to be developed from the ground up.
