No, nothing to do with morphs. Individual health issues (including parasites, internal or external) can influence sheds, as can inadequate hydration & humidity levels, & also having a recent meal* can cause a terrible shed.
*Digestion takes up the body's extra water, which is also needed when shedding- a healthy snake actually secretes moisture between the old & new skin layers just prior to shedding, unless they are dehydrated- then they can't do that, & they end up with a stuck shed. That's why it's best to avoid feeding when you see that a snake is coming into a shed.
