They're being a bit loose with their excuses. On 5/2/20, EK35 was flown by A6-EGE, a 3 Class B777-300ER. If you were booked in Business Class and had previously selected 1K, then it had been based on a 2 Class plane operating the flight. The change has lost you 1K and you've got what was left when someone/something got round to sorting things out.
Sometimes they'll use a 3 Class plane with 2 Class service, in which case you've lost on the First Class cabin seat at the whim of EK.
