Amazon USA Global shop listings on Amazon UK only go live to order after usa release date and will list as available to order only if Amazon USA still has stock available after release date that is why some listings on Amazon UK don't go live as Amazon USA sometimes is sold out before release date or amazon US has very little amount of stock available

You can tell the difference between UK and USA releases by the release date

USA is always a Tuesday
USA and UK releases always have different ASIN numbers when it comes to Amazon UK and Amazon USA listings

If this steelbook gets a trade wide UK release from Sony the ASIN number on Amazon UK will be different to what you see listed on Amazon USA
It's also possible it might be a retailer exclusive in UK instead and UK release not be listed on Amazon UK with amazon UK as the seller
Third party listings don't count as the seller is not Amazon UK
