No, that's a bad example. In Catholicism, the bodies of martyrs and saints were (are) exhumed and displayed all the time for the purpose of being exalted and venerated. Indeed, often pieces of their bodies are treated with awe, even ones as unseemly as a severed tongue.

The Cadaver Synod was a humiliation because Formosus's helpless corpse was subjected to a nasty show trial, and because after the trial it did get stripped, 'tortured', and thrown in the water. But the exhumation and display of his corpse in and of themselves weren't the point.
