I've owned that lens, and I think that's a very accurate concise description of its character.

I have and use that one presently. I think its pictures resemble the modern 50mm Summicron's at a glance, and I'm honestly hard-pressed to remember which one of the two I used for some of my favorite prints, shot on the same film, without looking at my notes.
If there's a difference, I'd say the forty's bokeh is probably smoother...more gradual in transition from sharp to creamy out-of-focus. My fifty's was kind of immediate in comparison; still gorgeous, though.
No experience with any of the older Summicrae, but I understand they're of noticeably different character.
