As an Australian who's been drinking Cragganmore downunder for quite a while, I believe the bottlings here have been fairly consistent over the last 3 or 4 years. Certainly the label and packaging has remained unchanged.
I believe Cragganmore is a unique malt in that one's appreciation of it is very much affected by what is or was already on the palate. Try a Cragganmore after dinner one night, and then the next night, have a dram before dinner. I have done this frequently, and found the "post-dinner" dram to be much more smooth, balanced, and "relaxed". Drunk before dinner, I notice more sharp elements (possibly the smoke or peat) that seem to be less obvious after a meal.
This has also been my experience with the Cragganmore Distiller's Edition. However, I haven't tried any independant bottlings to test my theory on!
I would be very surprised if UDV were shipping different bottlings of Cragganmore to different countries around the globe?
