And which firmware version? Everything seems fine here with H2O on 3.15.x/3.16.x

3.13 should work even better, but ... I can no longer easily test since I can't up and downgrade firmwares all the time. I should prepare a different SD card for each firmware version I guess, but so far it was not worth the effort.

The bit-ness of the PNG should not matter, everything is converted to the framebuffer colorspace anyways, only the eink driver will do its own calculations from there since in the end you only get 16 greys. (#000, #111, #222, #333, #444, ... #fff)
