If a 3D TV has DLNA does it also need to have bluetooth?

I've been having dificulty to find a 3D TV that has everything I want, for example Bluetooth and DLNA. But it seems to me that the technology is the same as bluetooth and more.I'm thinking of buying a Samsung TV and I have an iphone, there are apps that enables it to be used with Samsung TVs. Butwhat I really want to know is if having DLNA excludes the need for bluetooth on a TV.

Bluetooth would be useful for connecting a keyboard and mouse. The apps on the iPhone will work over Wi-Fi. For instance, if the Samsung and iPhone are on the same network, you can stream video from the iPhone to the Samsung. You can also control the TV using the Samsung remote app. If your TV supports it, you can stream TV to your phone from the TV.
