I definitely think Jean has leveled up since her initial encounters with Exodus. In the Blood Ties story Jean Grey is probing Exodus' mental defenses and providing information to Xavier and that contributes to Xavier besting Exodus. I'm not sure if it is in the scan that was posted (because we don't really see Jean doing it but Xavier tells Exodus that is what happened). I think that shows some tp strength for Jean. Xavier states to Exodus "You see, while held captive, Jean Grey was constantly probing your defenses and relaying that information to me. And I knew you could be pushed into defeat."
But in my opinion, modern Jean becomes the powerful "omega" level telepath during the Kelly/Seagle years when she is expanding her powers and trying to scan the globe for Xavier and further in Revolution -where no shields in existence natural or artificial can withstand her telepathic attack yadda, yadda, which led to Morrison's run where she was described as a grown up omega mutant, if she was a mountain she'd be an Olympus mons on Mars (Beast says to Scott).
The omega re-definition helps most of the characters because it keeps them from being overpowered. Exodus is an omega level tk but he's not an omega level tp. It gives him limits. The same is true for Jean and the rest of the omega mutants who have more than one power.
In my view Jean still has heavy lifting tk that was demonstrated often in the X-factor years and a few times here and there in the 90s and she still has the molecular level tk like we saw in X-men Red (moving the nano-sentinel out of Storm's brain).
