I'm not sure if paletted really work with ILI9341...I haven't tried yet, but from my experience of pulling pixels for saving and restoring for implementation of overlay / popup tought me, that over serial it is quite a demanding thing... it is not like the simple BW Nokia displays, even though founctionally it may work. The discussion with @Gordon at that time hinted to switch to parallel from serial to get snappy performance... Using ILI9341 controller's specific data transfer operations in combination with Espruino assembled code could speed up the process as well.
