Ive been buying anything I really like on disc. Lots of movies I don't really care about and can stream, but things I've really enjoyed I pick up on bluray.
I'm very familiar with the technology, the discs indeed are a slightly different color, and the drives have an entirely separate extra lens and laser assembly to read them.
You worked for poor people. Every single high end media room I've seen (3 lol) has been powered via blue ray. People with nice TVs have known streaming is garbage for years now.
