Of course you don't see any difference, this is how it should work. 'ls' will never report the compressed size, because it's not aware of it. Nothing is aware of the compression and decompression that takes place on-the-fly, except of course zfs. That's the reason why you could gain in write and read speed if you use compression, because the actual amount of compressed data that is being written and read from the pool is smaller than the original data. And I think with the checksum test you prooved that zfs checksums the uncompressed data.
No ZFS checksums are over the data as it is stored on disk so the compressed data.
