No, all traffic submitted through HTTPS is encrypted no matter what client your using. A client is any program (including your web browser). The only thing that is not enforced in non-web browser clients is HTTP strict transport security, which is something (I'd say) that needs to change. (If your site has HSTS enabled, it requires that all traffic is secured and encrypted. I would encourage everyone who's transitioning to HTTPS-only to get it; it prohibits people from visiting insecure versions of your site and submitting data there. Yes, an HTTP redirect can be set up, but HSTS enforces this requirement even if a redirect is not set up, and anything that makes your site insecure (i.e. invalid certificates or certificate parameters) makes your site impossible to connect to until the problem is resolved. At least, for web browsers, at any rate. This is because HSTS sites are hard-coded into your browser; once that's done, it will be impossible to connect to insecure setups on your domain (or any sub-domains if you set it up that way).)
