Is gold tier reward the pet "Romero" only? No tokens, chests, candy bags or any stuff besides the pet?

Are the locks in the platinum tier reward unlocked? If not, can they be changed into unlocked chests?

It would be much appreciated if each tier had unlocked chests (bronze 1, silver 2, gold 3, platinum 3).

Event tiers should be much better for this and next events, given most players focus on running until reaching top tier and not for lb so making these actually worth to get or at least a bit better would entice players to farm the event, there are many items that could help improve the rewards, jwl sacks, unlocked chests, small amounts of platinum, lesser/greater chests, event tokens, crate keys, crate tokens, etc.
