@Machinus: You *really* need to just read the documentation.
Do *not* manually insert files and/or rename files in the *active* pool yourself. And take heed of the "needs a restart" warnings.
----
Anything >= K4 actually runs an 8bpp framebuffer, with the quantization happening inside the EPDC.
Not that you should even have cared about that even on earlier devices actually running @ 4bpp. That's an implementation detail nobody outside of people talking directly to the fb (e.g., FBInk, KOReader) have to deal with (see earlier link).
That said, regardless of the target device, knowing the actual eInk palette is interesting when you want to dither your images properly first, like the cover mode does, because that hasn't changed since the K2. But it's not a hard requirement, it's just in order to achieve better (psycho) fidelity.
