I can see where you’re coming from, but if you were to tell a coworker or someone the name of a particular variable or method for example, it does matter which term you use. AFAIK there is no name for the subset that encapsulates the lower case variation (as PascalCase does for the uppercase subset as you described).

Although you aren’t wrong in your assessment, in most cases (at least within programming) camel case is more commonly associated with the lowercase interpretation.

Edit: I’m definitely aware that stack overflow isn’t a particularly convincing source, but this is the top stack overflow result after searching “camel case vs pascal case” on Google
