Moment of truth... I have successfully extracted epd service from Hisense's A9 InkOS stock ROM and have packaged it within LineageOS framework and services jar. Compiled it late last night and it's currently installing on my own A9. Finger crossed I can interact with it! If I can, I can change the refresh rate, clear on demand. Next will be to figure out how to change the temperature of the screen. But that's a challenge I can tackle later.
