Expected latency for LoL-Wild Rift?

My latency for League of Legends Wild Rift ranges from ~500-600ms, whereas I can play League of Legends on my laptop at ~30-35ms. Why is Wild Rift latency 17 times higher than LoL?

I have assumed that both game clients connect to the same Riot server, which would rule out geographical issues (playing on OCE from New Zealand if that makes a difference). Both games are using the default in-game settings. Both devices are wirelessly connected to a router with a fibre connection. The devices I’m using are a 2015 MacBook pro for LoL and a Samsung S9 with cellular data disabled for Wild Rift.
