HTTPS proxy means that the client establishes a TLS connection to the proxy and then communicates over that, which is different to the normal and traditional HTTP proxy approach where the clients speak plain HTTP to the proxy.
Talking HTTPS to your proxy is a privacy improvement as it prevents people from snooping on your proxy communication. Even when using HTTPS over a standard HTTP proxy, there’s typically a setting up phase first that leaks information about where the connection is being made, user credentials and more. Not to mention that an HTTPS proxy makes HTTP traffic “safe” to and from the proxy. HTTPS to the proxy also enables clients to speak HTTP/2 more easily with proxies. (Even though HTTP/2 to the proxy is not yet supported in curl.)
In the case where a client wants to talk HTTPS to a remote server, when using a HTTPS proxy, it sends HTTPS through HTTPS.
