To add to what epiclr4 said (nice to see you checking in once in a while, Heath) dealers do get an allotment of LR4s from corporate and they don't have much say in what corporate sends them. When I was ordering my 2014 last year the dealership was receiving 5 black and 5 white, all Lux's with black interiors and none with the dual transfer case/HD package. They had no say in what they got. I suspect that corporate schedules a bunch of trucks to go through the assembly line first. Usually these are trucks that are very common in color and options so they know they won't have a problem selling them.
As was said, you should be able to get an order sheet from your dealer that shows the date when it is to hit the assembly line. If they have a VIN then you can pull that info using the VIN.
