How our LR3s and 4s would do on this test?

Thanks, I have seen that a while back, some crazy stuff. But I meant the roller test (or real world situation) with only one front wheel with traction. Could that one wheel pull our heavy truck up a grade, the way that subaru is able to?

The Subaru video seems rigged. Every time a vehicle besides the Subaru starts to move forward the brakes are applied, as evident of the stoppage of all four wheels.
Also they do not show the Subaru's transfer of power, once the wheels start to slip.
I have seen this first hand, it react the same as the other vehicle when traction is lost, and the need to transfer power happens.
The Land Rover system works a bid differently.
Using open diffs and braking to transfer power rather than differential locking (only applies to those vehicle without locking diff).
the CDL on the LR4 and LR3 ensures that the front and rear wheels receive the same power instead of trying to vector the power.
Saves time.
The Land Rover system also reacts relative quickly. Watching the other AWD systems take "time" to resolve a loss of traction issue is a bit scary TBH.

The Land Rover video shows the same thing as the Subaru video, only more difficult.
Our LR4's would walk up that Subaru ramp, with maybe only a momentary pause. The ramp test is only difficult for vehicles that pay lip-service to "all wheel drive."

So the question is, just to be clear, can an LR3/4 send 100% of the torque to a single Front wheel (or a Rear wheel) if needed (in both versions, with and without the the HD package)?
You never need or want 100% of the torque going to a single front wheel or single back wheel. The idea with a CDL is that the torque remains evenly split between the front and the back, even if the entire front or back loses traction.
To explain it more than that, you really need to understand how the front, rear, and center differentials work. Look for youtube clips on that.

As ryanjl said no need or want for 100% of power at any wheel.
With the CDL on the LR4 it creates a 50/50 split front to rear.
Technically in this situation you could have 50% at any given wheel. Probably closer to 35% once you consider drivetrain loss.
However at 35% still much more available torque that most other, similarly capable, AWD SUVs.
Plus add the TR and it's ability to regard or advance the engine output as needed, it become one of the most capable systems put there.
There's a reason Ford, Jeep, Dodge, and other similar 4x4, SUV/truck manufacturers have also bought into the system.

The differential used in that model outback is very similar to the Torsen-C used in the single speed LR4, so I would assume that the LR4 should have no issue with it...
