UHD Blu-Ray .mpls Files Missing Metadata About Video

[disc-kuraudo]

Trying to get metadata about titles on UHD Blu-Ray Discs from the .mpls files, I only seem to get Info on Audio, Text(Subtitles) and Chapters. On normal Blu-Rays these also contain info about the video codec, e.g. AVC etc. I assume there might be Codec IDs missing for HEVC when parsing the file.

Here's a sample file from Titanic's UHD release a few months back, holding metadata about the main movie:
