Okay, now I remember why this stuck with me:

Because that happens on the Forma, which was my daily driver for a while.
That explains why I never went ahead with that idea ;o).
FWIW, while nightmode is terrible there, that works decently well on a H2O.
And on sunxi (which does sport the fancy nightmode waveforms), once you account for the ioctl sucking balls, it's not too horrible either.
(Wrong thread, but here's the
KOReader PoC for both sunxi & mxcfb).
Note that I'm currently in complete darkness, so I have yet to see how it fares in daylight. And how it works on Kindles, where I know lab126 attempted something like this, which apparently never made it into prod (Kindles >= FW 5.6 do not suffer from the double flashing issue, though, which helps).
