The cache purge caused by switching themes purges /everything/.  The 
"Pre-scaling Theme Images" that occurs on application startup only 
re-scales those /theme/ images that have changed since the cached image 
was created (i.e. where the filesystem timestamp on the cached image < 
the timestamp on the theme image).

As for cached metadata, I'm sure it works like the theme pre-scaling, 
but occurs during usage (when the specific scaling/image operations are 
known).
