It does. In that comparison gif, look at the highlights on 3POs arm, they exhibit the same sort of hard edges.
Not really, they exhibit some minor blooming that you might expect from an old telecine transfer. It looks nothing like the intensified lightsaber - and notice that it’s not just the highlights that have intensified on the lightsabler - the entire blue glow has widened, and this shouldn’t happen if it was the same on the telecine prints that it is on the theatrical prints. The usual practise of the day, as far as I’m aware, was to produce prints for telecine separately - you didn’t transfer theatrical prints if you didn’t have to. So telecine prints will have differences to them, however in this instance it appears they re-composited the effect so the blue glow would be more visible on the videotape.
Also, why wouldn’t this be the case with the other shots, like this one:
Poita’s scan:
“TB release”:
Or this scene:
No extreme glowing happening there.
