You have the right general idea about the nature of IFLA LRM. LRM is essentially a merging and reformulation of FRBR, FRAD, and FSRAD. It is not a metadata schema.
BIBFRAME is an implementation of RDA, which is a metadata schema based on FRBR. BIBFRAME is still under development, and is currently only used for development and experimental purposes. LRM is too new for any system to be called LRM compliant. Work is underway to bring both RDA and BIBFRAME in line with LRM. The new version of RDA is available as a beta release, but is still incomplete. Exactly how closely RDA and BIBFRAME will comply with LRM is to be seen.
I know very little about PREMIS, but I believe it has no relationship with FRBR or LRM. It is a metadata schema that views resources from a very different perspective.

Subject: [CODE4LIB] BIBFRAME, IFLA LRM, and PREMIS
Can anyone explain the relationship between IFLA LRM, BIBFRAME, and PREMIS?
From what I can tell, IFLA LRM is not actually a metadata schema. Rather, it is just a list of top-level entities involved in a bibliographic resource and how they are related to each other (e.g. a *work* has many *expressions*, and an *expression* has one *work*).
BIBFRAME is an actual metadata schema containing elements like title, author, etc. that describe the higher-level entities defined by IFLA LRM.
Except does it? BIBFRAME 2.0 was conceptualized in 2016, and the IFLA LRM was published in December 2017. If I were to use BIBFRAME today to describe a book, would that metadata be IFLA LRM-compliant?
My question about PREMIS is much the same. Is it compliant with IFLA LRM?
Furthermore, is it possible to catalog with PREMIS and BIBFRAME together?
For instance, if I have a BIBFRAME representation of a book at www.mysite.com/mybook, can I use that URI as the PREMIS Object?
Maybe these are questions that are not fully answered yet because of the lack of concrete BIBFRAME implementations.
