Lesser Black-backed Gulls, individual variation? Sonadia Island, Bangladesh January 2021 (1 Viewer)

Had a couple of Lesser Black Backed Gulls in a large flock of Pallas's Gulls. Noticed the difference in mantle color of these two individuals with the one on the left having a noticeably darker mantle. Could they be different subspecies, or just individual variation? Unfortunately only these two shots
