Yes, best thing to do is look for them in the 1921 census. If she was 6 in 1915 she'd be about 12 in 1921 so likely she was still in the convent by then.
My great gran from Oxford was also sent to a London convent and was baptised at a nearby church in March 1910 aged 14 and was working in service by the 1911 census in Bexhill, Sussex. Not sure how long she had lived there prior to 1910 but her mother died 8 years earlier, but her dad lived to 1927.
