A:Answer I can see why you asked but...
Magnolia is the area in the back of some larger Best Buys that has 'better' products and I believe a different set of product specialists. They have a darker environment that generally make the TVs look better. Magnolia is a Best Buy thing. I believe if a product has Magnolia on it's page, you won't find it at a 'normal' Best Buy.
Bravia is a Sony name that I'm thinking meant at one time that the set was one of their better sets, I believe all their sets are now Bravia. So Bravia is a Sony thing.
