Can it be you mean blank=as_needed ?
This applies default formatting to unformatted BD-RE.

Probably the difference is in the Sub-type field of the FORMAT UNIT
command. dvd+rw-format uses type 2 for "-format=full" and type 3 else.
The matching cdrskin blank type of cdrskin for Sub-type 2 would be
This formats to default size.
You may chose other format sizes by a further blank= option.
The latter refers to the idx numbers as listed by
$ cdrskin -v dev=/dev/sr3 --list_formats
BD Spare Area: 0 blocks consumed, 393216 blocks available
Format idx 0 : 00h , 11826176s , 23098.0 MiB
Format idx 1 : 01h , 11564032s , 22586.0 MiB
Format idx 2 : 30h , 11826176s , 23098.0 MiB
Format idx 3 : 30h , 11564032s , 22586.0 MiB

Format idx 5 : 31h , 12219392s , 23866.0 MiB
format_defectmgt_payload_... can be chosen quite freely. But extreme wishes
might lead to rejection of the FORMAT UNIT command by the drive.

For BD-RW this has the same effect as "as_needed".
It will make a difference with CD-RW (no action rather than blanking),
with DVD-RW (formatting rather than blanking), or unused BD-R (formatting
rather than no action).
Have a nice day :)
