You're right in the limitation of space aboard the 77W - but I think EY do a decent job of having a lavatory bigger than the standard size and actually pretty comfortable. The same can be said of their 346 aircraft as well.
If you look at Emirates or Cathay Pacific however - there are no excuses for a Y sized lavatory.
