Very hard to detect, so no not really. It is possible its something else but the rim is true and with no bumps.
I've tried two different QR's and crappy weenie one and a nice beefy HED one.
Just to rule out heatset or something else frame related have you tried a different wheel?
Different wheels have been tried and all found fine. Offending wheel has been tested in 5 different bikes and found to judder in all of them.
