Yes, and the Discovery 5s 2017-2020s have an extra button in the terrain response cluster of buttons. I don’t recall Land Rover’s name for it, but some manufacturers call it crawl-control. It’s like cruise control for off-roading. If there is only one button to the left of the height control (DSC on/off), that truck does not have the Capability Plus Package. If you see two buttons (DSC on/off above and crawl-control below) that truck has the Capability Plus Package.
If you have a TOPIx sub you can still check on any LR4 year that your subscription has access to. I paid for a month of it for all LR4 years while shopping. If I did it again I would have to be very serious about scanning the internet for a truck with that option. There are just so many more available out there if you don’t require the locking rear differential, that may have lower miles, lower price, nicer color w/black package, a better selection of options, or are simply closer to you. ...many, many more.
