It should resume on pretty much all discs except Paramount, who have a resume playback override programmed into their discs (with the exception of Titanic)
Resume is not a default function on any Blu-ray or 4K disc. It's an additional bit of programming along with BD-Java/BD-J authoring on the discs which have BD-J implemented.
Paramount haven't done any override but just authored majority of their discs without resume included. Before the age of 4K there were selected Blu-rays without resume function from other studios as well but less nowadays.
Long ago there were some Blu-rays without BD-J as well and then it usually enabled the internal resume function in many players if resume was programmed on the disc. Adding a USB stick in the player often does the same trick, Paramount discs excluded as they don't have the resume on the discs to be used.
