Some of the luxury features are deliberately left out in Toyota brand otherwise people would go for Aurion rather Lexus as Aurion has more features than any Lexus below $70,000. Besides Aurion has a much powerful engine than half of the Lexus, an engine that's used in RX350. Anyway, most of the design and features in Aurion are heritaged from/by Lexus except that it's built with cheaper materials.
