Good job! DLT logs are pretty standard in the infotainment industry, the format specification is openly available. I recommend you to download DLTViewer from GitHub and open the log files (if they are not encrypted). You may find good stuff there!
Author here. Yes, there is some good stuff in the logs, I found the Wi-Fi password there, that was useful. At the time I used some VSCode plugin to read the .dlt files (they are not encrypted), but later I did find that dlt-viewer on COVESA's GitHub.
