I think they should be, yes.
It's not completely out of the ordinary to get a first press item, especially depending on where you get it.
I got a first press edition of Ayu's "(miss)understood" album from YesAsia earlier this year and also the first press, digipak version of JASMINE's "NO MORE" single from CD Japan even though both places said both releases were out of stock.
Though, I think you're more likely to get lucky with YA than with CDJ since YA uses different suppliers.
