420SEL idle level

I recently drove my daughter's '88 420SEL and noticed that the idle went up to a steady 1,000 RPM when stopped in Park, but was steady at 600 RPM when stopped in Drive with the brake on (like at a stop light).

The car runs fine otherwise -- is the out-of-gear 1,000 RPM idle level anything to be concerned about?
