okay so lets ask the question another way.

   Hit Backend#1 directly; get GZIP'd content

   Hit nginx which then proxies to Backend#1; get raw content

Soooo ... either ... nginx is decompressing, which you claim it is not, 
which leaves that nginx isn't passing on all the HTTP headers to the 
backend, including the all important:

   "Accept-Encoding: gzip,deflate"
