For your KLM question I flew on PH-PVK and PH-BVP last month and they both had the New World Business Class, the B772 fleet was updated before the B77W fleet and that is now finished:

https://www.klm.com/travel/us_en/pre...lans/index.htm) does not show the B777 with the old seats anymore only the A330.
