For high level area controllers the wake vortex category is irrelevant,you'll get 5 miles and 1000 ft separation. Although you should state heavy or super on first contact,I believe this is also an ICAO recommended practice. The aircraft type on approach is because it has happened many times in the past where a short notice aircraft change has not been put into an amended flight plan. The plan says A320 but a B767 is being used. Not an issue for you,potentially very much an issue for the crew right behind you on the approach.
