Exclude records with empty binary column data

I have a column with type binary(16) not null in a mysql table. Not all records have data in this column, but because it setup to disallow NULL such records have an all-zero value.

I want to exclude these all-zero records from a query.

So far, the only solution I can find is to HEX the value and compare that:

SELECT uuid
FROM example
WHERE HEX(uuid) != '00000000000000000000000000000000'

which works, but is there a better way?
