You're 100% correct, I'm a dumb-dumb, because I should have known that.

Interesting I tried doing it and all I got was this error

X Error of failed request:  BadMatch (invalid parameter attributes)
  Major opcode of failed request:  73 (X_GetImage)
  Serial number of failed request:  1010
  Current serial number in output stream:  1010

I did it both on a Ubuntu machine (remote) and on a Fedora machine
(local), and it came up with the same error.
I added myself with xhost and the display was set. I also gave the
correct window id. 
In this case I used xwininfo -name Firefox to get the id of just
Firefox.
