Most engines are assembled just prior to being fitted - possibly 2-4 weeks in advance - and part supplies aim to be just in time. But yes the crankshaft and bearings would be batch produced and so will take longer for any changes to flow through.
Any crankshaft design and manufacturing changes could have gone into the MY19 and MY20 Discovery 5, but it may be too early to know if this was successful. Regardless, the D5 service intervals won’t be helping.
Different story for crate engines intended as spares though - these clearly need to be pre-built.
Hopefully Art can find a date and time on a tag somewhere on the replacement engine as it will be interesting to know if this is old stock or a more recent build.
