I thought you generated the key pair on your device and never sent the private key, not even to WhatsApp? Isn't that the idea behind the Signal protocol, which WhatsApp uses?
That's the theory. The closed source nature means that the WhatsApp app could send the key back to WhatsApp. How would you know if it does or doesn't?
Analyze the traffic between your phone and the Internet?
Several encrypted packets went to WhatsApp servers. Did they contain your key?
