Gemini is likely weighting marketplace domains as 'trusted neutral aggregators' over vendor-owned URLs—it's a trust signal, not a schema parsing issue. Test adding schema.org/BrandAccount markup on your DTC domain linking to your official brand profile, plus explicit schema.org/sameAs relationships on your Product markup pointing back to your canonical URL from the marketplace listings you control. If Gemini still prioritizes Amazon, you'll need to build inbound citations from high-authority retail/review sites linking to your DTC product pages to shift perceived authority.
