How should we label Wang Lin images when his age and form keep changing?

Wang Lin cannot be identified from hair color or one forehead mark alone. His face, clothing, age presentation and cultivation context change across the story, and heavily redesigned fan art makes the problem harder. I think every reviewed image should record an approximate era or form instead of forcing all portraits into one timeless character label. In this phone wallpaper, which cues feel stable enough to identify Wang Lin immediately, and which details might belong only to one stage of the adaptation?
