CLOS is wierd since it sits in a multiparadigm language, so CL really spans boxes. JS is the same as well depending on how you use it. Smalltalk is a great example since it really did manage to do OOP x dynamic in a much better way and its worth wondering why Smalltalk pulled it off where Ruby feels like a nightmare. I suspect it has to do with focusing on the message passing aspect.

So no, it's not a perfect model, but I think its more informative than looking at languages on a one dimensional static / dynamic axis.
