Despite the glxgears specific issues, the answer is "yes" ;-)

Cygwin defaults to software rendering (but that's only relevant for
local clients)

The problem is not that the software rasterizer is limited to 1.4 but
that indirect GLX is. No matter what the local cygwin server (you may
enable experimental WGL) or the remote nvidia server can do. A remote GL
client can only make use of 1.4.
