I'm from a small town in Saskatchewan and it was the last Splatoon bundle they had anyhow. Looking at reported serials I think the Splatoon 2 Bundle has a good chance of being <= 3.0.0 (none in the spreadsheet are > 3.0.0)
At best its a gamble, but I'd bet on it being 3.0.2.
HexZyle has put a great image together (a few posts up). You'll notice that XAW700094 falls after the introduction of 3.0.0 atleast, possibly after the reported 3.0.2 console XAW7000928XXXX. Looking at the spreadsheet the last 2.3.0 reported...
