Yes, you've got it spot on, and that's what REALLY annoy sme about this programme - all the cutesy little vocalisations that are dubbed on for dramatic effect.
Take, for example, the caribou calf being chased by the wolves. It was bleating away. Miraculous sound recording, seeing as it was filmed from about 1km away. When something is being chased, it doesn't bleat in a heart-tugging telegenic fashion, it's too busy breathing to keep its legs pumping.
And the polar bear cubs: cub falls over, cue cute cub snuffle noise.
And the snow leopard: capturing footfall sounds across a valley, eh? Unlikely, seeing as snow leopards have furred feet, so they don't even make footfalls.
It really really annoys me, as it is dishonest, and it is purely for dramtic effect. Virtually all of the sound on there is dubbed on, none of it is real, and it isn't even used honestly. The BBC seem obsessed with this, and they should sack the geezer doing it. Not only did they mess it up with the snow leopard, but on another programme on BBC, about Springwatch's barn owls, they actually dubbed in wing flap noises for flying barn owls. Barn owl wings, swishing!
And while I'm ranting, I also noticed a factual mistake in Planet Earth: in the sequence with African Hunting Dogs, they claimed they are the rarest carnivore in Africa. This is not true, as that accolade belongs to Ethiopian Wolves, which were even featured in the same series. There are about 3-5000 dogs, and about 500 wolves.
Makes you weep when you think back to Living Planet and Life on Earth, doesn't it?
