Yes, of course it seems like a more tricky season on a structural level because although it has a more marked focus from the beginning (taking Grogu with the Jedi), it also takes advantage of that focus to pause in more adventures and secondary plots.

Regarding chapter 4, I also thought for a moment if it would be important to include it in order to establish the empire’s intentions with Grogu, which may have importance in the future. But for now the setting is so slight that the important thing would be what we see properly in the future.

And about the sound, I notice it especially at the end of the film: when Luke is leaving with Grogu in his arms and the music plays quite strongly, I notice a watery sound in the background. I have seen the .mov version, if you want I can check if I notice the same in the .mkv.
