Stagecoach MCSL - Chester & Wirral Depots

RE: Stagecoach Chester & Wirral
Recently, I've noticed that the Chester park & ride services can yield pretty much any vehicle. At least one of the vehicles previously painted in the dedicated P&R livery has been painted into standard colours & today I noticed a Dart on the 32.

Now whilst I didn't have much time for First when they were in charge, they could at least keep the P&R service running with dedicated vehicles & it was unusual to see anything else on those duties. It seems to have become a free for all in the last six months or so.

Does the contract with Cheshire West specify that the vehicles used on P&R services should be the branded vehicles?
