However, in your example, the fact that it was created under ESA 4.3 and is still in use under a current OS level doesn't really mean anything. There has been code in the past that changed the catalog/catindex once it was opened under the higher level. When this was the case (and ESA V4 dot something may have been one of those versions that changed it) there were toleration PTFs to allow the lower level system to share the catalog. If you were sill running a very old system and created a catalog that would then get touched by z/OS 1.8, there is a chance that any code that changed the catalog / catindex may not still be there.
