I agree WOB is a great tool, I use this all the time as well. unfortunately with these subtle morph even with a picture you really don't know what you're looking for. I have seen on some sites where they would make colored circle around a particular markers and explain what you should be seeing, Ex flames of YB.

The breeders would be of great source but I would be reluctant to keep asking, you would need more than a few questions and follow up questions to see what to look for.

Which brings me back to my point, if we can have a compilations of subtle morphs that have consistent markers that would certainly keep us off these breeders back I understand and agree some of the morph you cant tell apart and you need to get it from a super form breeding to be assured.
