Just looked up the price online for those WPC bearings, seems cheaper than BMW OEM parts, any downsides to these or are the genuinely an "upgrade"?

It's hard to say if it really makes any sort of actual difference. In theory bearings are a no-touch item anyways. Pricing for WPC treated bearings should be higher than OEM - WPC is a treatment done to the OEM parts. I'm guessing the difference you saw is based on two different sellers.
These videos from MotoIQ show some more detail on WPC. It's one of those things that was only marginally more expensive but *could* have a positive benefit, so I went for it.
