I had not tested, nor highlighted those cases (working tree only, for log https://smartgit.userecho.com/en/communities/1/topics/1438-files-view-log-denote-lfs-files):

added: LFS icon

unchanged: LFS icon

modified: LFS icon

staged: LFS Icon

untracked : no LFS icon

Looking at this with the Log window.

Graph: Working Tree/Index is selected, unchanged OK, staged OK

Graph: any selected commit, no LFS icons.
