4k blocks is what to expect unless you are using larger pages.

" -b block_size_options
This option specifies the fundamental block size of the filesys‐
tem. The valid block_size_options are: log=value or size=value
and only one can be supplied. The block size is specified
either as a base two logarithm value with log=, or in bytes with
size=. The default value is 4096 bytes (4 KiB), the minimum is
512, and the maximum is 65536 (64 KiB). XFS on Linux currently
only supports pagesize or smaller blocks."
