I have seen variations in both over the years. As I am aging a lot of both, I'm not worried about it. In the early 2000s, I'd say they were more consistent than they were by 2010, when I'd get batches with different shades of colors in both blends.
Btw, I've noticed inconsistencies in several Esoterica blends as well, with Stonehaven being the most variable over the years.
