Are the pre-selection menus the same as the onboard menus?

Flying HKG-LAX and the only two decent options on the pre-order menu seem to be the Prawns and Scallops or Chicken.

If it’s the same as the menu onboard fine, but was hoping for maybe something different. If I pre-order and then want something different will they just give the pre-ordered meal to a nonrev?

And is 14J that bad? The thought of less foot traffic from just row 15 sounds nice.
