Can that same method be used to figure out what files changed between snapshots?

Wout.

I haven't found a way to report in human terms what the above object
refers to.  Is there such a method?

There isn't any great method currently, but you can use 'zdb' to find
this information. The quickest way would be to first determine the name
of dataset 0x1b (=27):

        # zdb local | grep "ID 27,"
        Dataset local/ahrens [ZPL], ID 27, ...

Then get info on that particular object in that filesystem:

        # zdb -vvv <dataset_name> 2402
        ...
            Object  lvl   iblk   dblk  lsize  asize  type
              2402    1    16K  3.50K  3.50K  2.50K  ZFS plain file
                                         264  bonus  ZFS znode
                path    /raidz/usr/src/uts/common/fs/zfs/dmu.c
        ...

The "path" listed is relative to the filesystem's mountpoint.
