not likely, especially the trim number, I've never seen any decoding for what's on those tags .... all the paint chips I've seen for 57 are in the 700 range .... but I doubt someone switched the tags or the factory got it wrong, we just don't know what it means, like it may be a color + pattern instruction for the line
for 57. a 781 paint code would be a 2 tone, Alpine Blue and Bombay Ivory
