I think you are right, The closed SDK are an issue and latency will never be as good in third party apps without that.
Still I think latency of the note apps is not on the pen side but on the screen redrawing side, and to my knowledge 10.3 ereaders all use the same Eink Mobius display.
Once in a while I run into a bug which causes third party apps to show considerably less redrawing times (and of course, a lot of ghosting, but a better pen experience in stylus apps), I think the trick to reducing latency for developers could be as simple as allowing ghosting in "fixed paper" apps... I think that's why the native apps in the Mimas don't have pan and zoom, it is a fixed canvas.
