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.

> unpainted wooden

can you please elaborate on this? logic dictates that if you cover the whole thing with plastic (paint) it will affect the performance of the material (I assume reflecting light (paint) vs absorbing light (raw wood).

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