I've read on a few occasions that the Pali used in the commentaries is more difficult to decipher than the Pali used in the Pali Suttas.
Is this because of the introduction of new concepts and/or is it the result of some kind of structural or grammatical transition?
Metta,
Retro.

The structure of sentences is often more complex in the commentaries than in the suttas. It is not necessarily more difficult. But it is different. And since tutors centre on the sutta style, the transition to reading commentaries can sometimes be a little difficult. When I started learning Pali and had worked my way through Warder, I thought I could read Pali fairly well - but then the commentaries hit me like a ton of bricks!
Well, after the first shock I found that most of the commentaries are not so difficult after all. Sometimes they are very clear and logical in structure. But someone really ought to write a tutor for commentarial Pali. Pali needs a book similar to Gary a. Tubb and Emery R. Boose: "Scholastic Sanskrit". But Pali and Sanskrit are so close that if you know some Pali, "Scholastic Sanskrit" can also be useful for dechifring the commentarial idioms in Pali.
