You can 100% achieve a real temperature difference with unpainted wooden internal blinds. I'm sure you can achieve much more with an ideal setup but just sharing from experience, what OP has can easily make a difference of several degrees.

I think you should read it as "even with unpainted wooden blinds". The right paint should indeed be better.
