If you can try asking the seller. Most shops allow you to test a console before purchasing it so just try aking the seller if you can check it beforehand
I read this on wiki "On March 9, 2017, Sony released the next major firmware update, version 4.50." So any bundle before march 9 will have 4.55 and below this bundle im not so sure about since its quite new. You could try the older bundles.
