Found this on playstation site

As mentioned previously I've preordered the ps5 through a relative in dubai.i haven't owned a PlayStation in years so I don't have an account.

So my query is if I buy miles morales ultimate here in smyths for example will I be able to download the dlc or will it be deemed incompatible. Or once I setup the ps5 and my account as Irish will I be set to the Irish ps store
The account is completely separate from the physical location you purchase the console. Once you get it and set up an irish account, you'll be able to redeem irish codes, i.e. anything from smyths here will work
