@frostschutz: Yeah, even on my unopened one, the fit of the top edge of the bezel/IR array is atrocious :/.
11px is the value Nickel itself blacks out, to avoid any possible nitpicking on that front (i.e., I shift the blame to Kobo ;p).
That works out fine on my end, I can maaaaaybe see one or two of those if I look at it at a reaaally shallow angle (like, err, when it's sitting next to the keyboard during tests ;p).
. But then you start to see fairly weird crap everywhere at that angle, plus the reflections off the IR casing
.
In any case, that fudging around is togglable, to restore the previous behavior
.

EDIT: Stupid idea of the night: one could use the nightmode hack as a skeleton on which to base something to forcibly black out those pixels in Nickel: interpose updates w/ top=11 & height=1429, and possibly add a bit of targeted memset if Nickel also skips writing to those entirely, and not just refreshes
