No, that is not correct.
"But the acceptable way of worshipping the true God is instituted by Himself, and so limited by His own revealed will, that He may not be worshipped according to the imaginations and devices of men, or the suggestions of Satan, under any visible representation, or any other way not prescribed in the holy Scripture." WCF 21.1.

Getting back to the OP: Doesn't the RPW only apply specifically to what goes on during a stated Lord's Day worship service?
