no, the slaty-back is and looks totally different: https://scontent.ffra1-1.fna.fbcdn....=7e61c82b6ce72370dc4660cb0d7b9ce7&oe=5ED4C1F1
there are some GBBG with a slightly paler mantle. in newfoundland you can get glaucous gull x GBBG hybrids but this one doesn't look like such a hybrid. to be 100% on the safe side you'd need an open wing shot, though.
