I thought I'd seen those in stations of a different Asian metro...had a look around for photos.* In the few systems I checked, 3D maps can be seen in Beijing Subway,[1] Seoul Metro,[2] and Shanghai Metro;[3] plus this station in Tokyo, albeit a rail-metro station.[4] Tokyo Metro also has detailed, unusually discoverable 3D maps online.[5]
Counterexample: Guangzhou Metro doesn't seem to have any, despite its modern look.[6] Speaking of which, these new systems all look remarkably similar. Is there only a single manufacturer of platform screen doors and tactile paving? Even Delhi Metro, with very few photos, has that same look in its newer stations.[7]
* Turns out, image search (every service) fails terribly at this: All the results for maps are system maps; can't tease out a single station map for most systems. Photos of station interiors should show the actual posted maps, then? Nope. 90% of results are identical shots down the length of a platform. Turns out, it's Wikimedia Commons to the rescue
