I think this depends upon the brand and their marketing strategy. Amazon don't want you to think about their design, which includes dark patterns, as their brand is about making purchasing easy. For companies like Apple, being "designed" is part of their brand strategy, they push it as a differentiator and worth paying over the odds for. Doesn't matter than everything is designed, for Apple it's about being very conspicuously "Apple design", which people pay a premium for.
