As said, Control 4 is not a source like your cable box or your Blu-ray Disc player or your Smart applications on your television.
Control 4 is a very good remote control. It is a glorified universal remote control - that can do a ton more than your average 'really good' remote control.
If all you need to control is your Samsung and a cable box, then it may very well be overkill.
If you have lights, a Blu-ray Disc player, a cable box, and have all your equipment hidden away... Then it is STILL overkill to go to Control 4.
If you have a lot more stuff that you want to control, then perhaps Control 4 is the right solution.
But, understand that your Samsung TV can't do what your car does.
It also can't do what Control 4 does.
They are very different products and have completely different purposes.
