Wildcard queries are NOT analyzed. So the fact that your queries that are identical except for case produce different result sets is expected behavior. I believe there's a JIRA to allow limited analysis of wildcard queries, but I confess I don't know what the status of it is.
You'll have to do whatever normalization you need to do at the app level before you pass the query on to Solr or write a custom component to deal with this case I think.
