The whole point of write protecting them is that you can't recover the ROM contents. Well, you can always strip off the plastic and image the bits, but that's a whole lot more expensive than writing your own code...
Won't work on most PICs, which use EPROM, EEPROM, or Flash memory cells. There's no optically visible difference between cells storing a 0 vs. a 1.
Not by looking at them, but you can optically or eddy current probe them:

'Imaging', does not imply visual. You can get the data with a SEM, but the cost is typically perhaps $20000+. You also then have to work out where each 'bit' resides in the physical memory structure.
