The specs do vary by country. It doesn't surprise me the UK ones are different. Historically the German market has all the Seat / Cupra goodies. The place to look for goodies not in other markets.
Generally you table by country the options and what is in them. Only for research purposes unless a personal import is on option. For the UK, the Eire options can be interesting. Ofcourse Australia and NZ are right hand drive which you would think are equivalent to the UK. The whole VZclassification are marketing levels combined with specs. Seat had the Xcellence which then got changed to something else... Cupra got the VZ initials and classification but as said regionally what's in the package may be different by region.
