Apparently, at the back end of 2022, the dual boiler got a bit of an internal update. They changed both the brew and steam boilers and all of their sensors and tubes to compression fittings.
The serial number is on the box and also just inside the cavity where the water tank goes.
This is an example serial with a build of 2022 week 37:

I was looking to get a black truffle version but all the stock I can find were built in 2021. Has anyone in the UK seen one of these newer builds in black? I guess the stainless ones are more popular as there are plenty of those around built in 2023.
