A teardown of the new Huawei P30 Pro shows that all four sensors that make up its vaunted camera system have all been supplied by Sony. Although not unexpected, it does dilute the "co-engineered with Leica" branding featured on the device.

Diluted? The Sonys are no more diluted than Leica branded Panasonics, in fact the only decent sensors in Leicas are from Sony, those from Towerjazz are Canon level or even worse.
Regarding the CFA, there's probably some sort of mistake, the main sensor should be RYB while the secondary (presumed referring to the UWA) is regular RGB.
