Effects of the Rings of Power

[Nils]

So would they still confer the "thin, stretched" feeling of the others?

People became invisible because they were being dominated by Sauron. Dwarves could not be dominated because Aule created them that way, therefore their rings did not make them invisible.

Dwarves who had the rings did not have their lives increased. They still died of old age.

No invisibility = No increased lifespan

Therefore I'd say that the Elven rings did not "confer the 'thin, stretched' feeling of the others".

I believe the 'thin, stretched' feeling is fading. As an incarnate being ages, its body gets consumed by its soul. In Middle-earth(outside Lothlorien under Galadriel's influence while using her ring), the fading process occurs much more rapidly than in the Blessed Land.

A mortal, Frodo, who keeps one of the Great Rings, does not die, but he does not grow or obtain more life, her merely continues

Obviously a mortal who wears the rings does continue to age. They don't die. Therefore literally they do get more life. Yet it is an unnatural life. They don't get more natural life. Their bodies are consumed and they become wraiths.
