From your updated description, you're referring to the 1st screen (sometimes called "splash"). It's encoded and built into a separate partition of the device (not /system), which can't be changed easily. Only on popular devices can devs bother to figure out the location and the format of the stored logo, thus making it accessible to us modders.
