Is there a significant difference in production costs for Live Action vs animated OP/ED?


With the anime _Desert Punk_ despite the fact that the anime is animated, the
Opening is in fact live action. To me this seems kind of odd.

So, I am wondering if there are any other anime which are animated yet use
Live Action Openings/Endings, and if it's significantly cheaper or more
expensive to produce a Live Action OP/ED rather than doing an animated one.
