Look, if you want to to use 4 oz of olive oil in cooking, making Olive oil powder actually increases the weight of the olive oil slightly. Just think about it for a second; you are adding more weight to a defined weight. Nothing is "going away" or evaporating, it's just being absorbed by the maltodextrin. I suppose you could make that up in the container you put it in. But, really this is about creating different flavors more than a backpackable powder. Personally I have never had my liquid olive oil leak on me while backpacking and the container I carry it in is under 2oz no matter how much I bring in with me. That said, you can come up with some cool flavor combinations using the powder, but I wouldn't fry my trout in it.
