Good question, unless it says rear axle steering inoperative, if no message and not working, maybe the car really isn't equipped with the option, time to check the window sticker.

First off, what makes you think it isn't working? Assuming it's a W223 given the section you are posting and that for some strange reason it wasn't dropped at the factory, AMGs rear wheel steering only turns up to like 3 degrees. It's fairly minute and may not even be noticed visually when stationary. It doesn't do the crazy 10 degrees that the regular S Class does. I remember a similar thread a while back. Somebody with a GT 63 also thought it wasn't working until they realized it only turns a few degrees.
Having said that, it is in many ways just another thing that can break. I drove the new GT 63 2-door coupe last year at an AMG event, so we were beating on it. Half way through drifting it, the RWS threw an error and after that it didn't work anymore and couldn't activate drift mode anymore. The error message went away after restarting the car, but drift mode still refused to activate. Wouldn't expect it to be faulty right away on a brand new car, though.

That's not true. You can see the rear wheels turn while stationary, for example during parallel parking. Wouldn't make sense if you are parallel parking and the rear wheels only start turning once you are moving. That would make for an odd delayed steering correction off the line. But as said, it may be barely noticeable if it only turns a couple of degrees.

You can see it, it's not obvious like the 10, but it visibly turns. You don't want to worry about hitting anything, so pull out into your driveway. Roll down the window, stick your head out, crank the wheel lock to lock while slowly backing or going forward. Don't open the door for a better view, for reasons known only to MB's engineers, the rear steering does not operate with the door open. Or at least it didn't at the time I had mine.

I ordered the AMG pkg which eliminates the 10 degree option due to the larger wheels and tires. . So I ordered the 4 degree.

Like Porsche, AMG does RWS for performance and not utilitarian purposes such as maneuvering around in a parking lot, and it's meant to be imperceptible. As such, less is more. The 10 degrees in the regular S Class is kinda like driving a forklift. Ferrari probably has the coolest RWS in the new 12Cilindri. It can turn each of the rear wheels independently at different angles, but they don't use it to actually steer the car. Instead they use it to dynamically adjust the rear toe and make the car do what the driver asks of it.

It can be hard to tell the difference with Porsche. I always get it on my cars, and with a loaner I could barely tell the difference in the lots. It's also subtle on the road, maybe the biggest difference being on the freeway and changing lanes: With rear steer, the car kinda goes on a thought; hard to describe if you haven't owned it.
This car with the ten is game changing; you really have to horse one around in tight spaces for a while to fully appreciate it. On the other hand, it is like you're constantly stepping in something squishy, that's deflecting your foot a little to the side, when on the road. Combined with the completely souless one finger steering in the S580, even up to the day I turned mine in, I never really developed a feel for the steering. You tend to just learn how much to turn the wheel to get it to go around a corner of whatever radius. I'd absolutely get it again because I'm not buying something like the S Class for road feel, but it's odd the way the tuned it. If they did nothing but toned it down once you're above lot speed, it would have all the advantages without the stepping in poo sensation. It was a head scratcher to me as to why they have it set up this way, I couldn't see the advantage.

When friends are in the car with me and I need to do a U-turn on a two-lane street, or wiggle into a tight parking space, they are amazed at the turning radius for a car this size. I have an S580 with 21" wheels, so I get 4.5 degrees, not the full 10, but even still, it's amazing.

I was going to say the same thing! I have a 2022 S580 and a 2021 Audi RS7 and the RS7 rear wheels turns more noticeably for sure. Glad to hear its working.

Having owned a car previously that changed steering ratios based on the drive mode and speed, which is what is essentially being proposed here, I have to say NO. I had the Dynamic Steering in my previous Audi RS5 and it changed the ratio based on how fast you were driving and also what drive mode it was in. In Dynamic mode (not to be confused with Dynamic Steering) it has a short fixed ratio, but in Comfort and Auto mode it changed the ratio from as low as 9:1 to 18:1. Basically at low parking lot speeds the steering was very direct for easy maneuvering and at higher speeds it became more indirect for higher stability. In principal a good idea and it was very easy to maneuver around in parking lots, but it resulted in inconsistencies while driving as based on the drive mode and the speed it took different steering angles for the same radius turn and it was jarring whenever I changed drive modes. RWS already sort of does a similar thing. At lower speeds the front and rear wheels turn in opposite directions in order to virtually shorten the wheelbase, but at higher speeds they turn in the same direction to lengthen the wheel base and increase stability.
