Quick answer: Unity Addressables Content Update including code changes but skipping texture-only updates? Content state hash doesn't detect texture binary changes - force update via Modify In Group.
Updated a single texture; ran Content Update; texture-only update not generated.
Modify the texture's group
Change the group's settings (compression mode); regenerate content. Forces detection.
Or use Check For Content Update Restrictions
Tool report; explicit per-asset diff. Marks texture for inclusion.
Audit content state generation
Content state file mtime; verify it updated after the texture edit.
“Content state detection is content-hash-based. Some changes aren't detected.”
If updates skip assets, the content state regeneration is the diagnostic. Force; verify; ship.
