I don't know if there's already been a thread about this, but here goes; I really thought DVD Player would die... And in fact, if you search for it in Launchpad, it isn't there anymore. So I thought it was already gone. But just to be sure, I popped in a DVD, and I got very surprised. A new logo greeted me; The DVD Player followed the System Dark Mode, and what do you know? It was a 64-bit Application. I was surprised to say the least. Now that you're at it Apple, add Blu-Ray support please. Here's a screenshot proof.
