H.264 Blu-ray movies, profile & level?

[eddman]

I'm trying to workout the differences between h.264 blu-rays and their respective h.264 MKV releases.
What are the profile and level of h.264 blu-ray movies?
How can I know a h.264 MKV file's profile and level details?

blu-rays and their respective h.264 MKV releases. Closed per rule 6. You can't talk about "releases".
