Jevons paradox is a veridical paradox, which, as you said, means that it's a true statement that merely looks wrong because it is counterintuitive.
I know that some people think that the word "paradox" should be only used to refer to antinomy paradoxes which are often called "true paradoxes" (such as "this sentence is false") which lead to a contradiction without requiring a flaw in reasoning.

There is no paradox, simply (a/b) increasing tells you nothing about a nor b. Jevons only “destroys” the (wrong) intuition that total b would decrease
"paradox" is an overloaded term.

Thank you for a great comment; I learned two new words today!
