I don't think I did, but please explain :)

The last example in my list of four file sizes is them in a folder. Filesystem compression works at the file level, so you have to turn many-almost-identical-files into one file in order to benefit from it. ZFS does have block-level deduplication, but that's it's own can of worms that shouldn't be turned on flippantly due to resource requirements and `recordsize` tuning needed to really benefit from it.

you do not need dedup just use reflinks for everything. if that workflow does not work then eh i understand why you would use zips

although zfs dedup is probably better in 2025
