I realized I've never explained a part of how I play with Yukari. This makes me an asshole. Allow me to rectify.
When Melisson uses telepathy, I imagine it as something like a whisper. Something you can feel inside your head, but feel it on your ears, your hair, the base of your spine. She's in you, and she's pulling on all your senses. It's organic, almost tangible.
When Yamataians use telepathy, I imagine (and described) it as "metallic." I'm not original in the idea — if you've ever seen Ghost in the Shell: Stand Alone Complex, the encrypted digital communication the characters use has this strange distortion to it. That's the distortion I have in mind when Yukari uses and receives telepathic communication (because, after all, Yamataian telepathy isn't "telepathy," but something based in digital communication).
You don't have to apply this, obviously. This is just how I think of it.
Also: Do you know how hard it is to find a damn example of it? I'm finding it too difficult to bother.
