I don't think so. It will be difficult to come up with a set standard.
I think a single morph can vary from one end of the spectrum to the other quite easily and can be equally beautiful. If there was a standard, then there would have to be a set way a morph will look like. Pastels alone can throw very different looking offspring in a single clutch. Some with busy jungle patterns, others with reduced banding, etc. Color and blushing differ as well.
However, I believe there should be (and there are unofficial) set guidelines to excellent examples of morphs. (Bright contrasted colors, lots of blushing, reduced pattern, etc etc).
I don't know. This is a hard post to respond too. Great topic!
