No, at least on SuperMicro it's a hacked up VNC protocol.  It's not 
embedded in HTTP/HTTPS, it just uses HTTP/HTTPS to fetch the Java app.

I say hacked up because it's got a custom auth method, and a whole bunch 
of undocumented extensions.  I looked into implementing support in noVNC 
for it, but reverse engineering a binary protocol is a bit beyond me.

It's also annoying because it claims to be a TightVNC server (and uses 
TightVNC auth/tunneling)... I was so hopeful that would just work.  It 
looks like they took the TightVNC code, and just made a bunch of changes 
with no regard for the specification.
