The 380 on YYZ is 12/76/395 config IIRC, so yes about 20% of the plane was Gold.

I was more surprised by the relatively small number of Golds on the Accra run where it was not uncommon to have 50%+ of Gold members in Economy until last year - although I expected this to reduce with the Skywards changes this year. It seems that a lot of the trader traffic is migrating to Turkish Airlines nowadays and the EK flight was almost entirely composed of Chinese migrant workers going to Accra and Bangladeshi peacekeepers going to Abidjan.
