Has the Catholic Church ever made an attempt to reconcile the attributes of the Universal Church as mentioned in the Apostles' and Nicene Creeds?
There is no need for the Church to do so. At the time of the formulation of these Creeds, both Greek and Latin were written in capital letters only. Only later modern versions wrote in lower case letters.
Lower case letters in Latin were developed in Middle Ages.
The lower case (minuscule) letters developed in the Middle Ages from New Roman Cursive writing, first as the uncial script, and later as minuscule script. The old Roman letters were retained for formal inscriptions and for emphasis in written documents. The languages that use the Latin alphabet generally use capital letters to begin paragraphs and sentences and for proper nouns. The rules for capitalization have changed over time, and different languages have varied in their rules for capitalization. Old English, for example, was rarely written with even proper nouns capitalised; whereas Modern English of the 18th century had frequently all nouns capitalised, in the same way that Modern German is today. - History of the Latin script
The Greek lower case letters developed in the nine to tenth centuries.
Greek minuscule was a Greek writing style which was developed as a book hand in Byzantine manuscripts during the 9th and 10th centuries. It replaced the earlier style of uncial writing, from which it differed in using smaller, more rounded and more connected letter forms, and in using many ligatures. Many of these forms had previously developed as parts of more informal cursive writing. The basic letter shapes used in the minuscule script are the ancestors of modern lower case Greek letters. - Greek minuscule
For example, capitalization of "Holy Ghost" can not imply a Trinitarian theology, all it says is that the translators think it is a proper noun. There are many theological positions which would identify "Holy Ghost/Spirit" as a proper noun without accepting Nicene or Chalcedonian Trinitarian theology, such as gnosticism, modalism, Arianism, Mormonism, and many more. This is equally true for Capitalizing Catholic which simply means Universal and vice versa. The official Orthodox Church often uses the word Catholic (Universal) in their Church title. This is not an issue for the Catholic Church.
