I personally think that Shopify can improve their work, but I do n’t know why they have not done better. The sub-url settings can undoubtedly absorb the juice of the parent domain, but the premise is that you must make verything perfect. Even if Google does not judge that as repeat content, but is not enough for you to repeat the page. If you want Google to give you a higher ranking, then you must be authoritative, otherwise it is useless, as if you claim to be a first-class product and service, but no one sees you and uses it, then all your work is nothing.
