One needs to use them in their personal lighting situations, not in a store.
I have both the current and prior iPad Pro version. IPS+Mini LED and the Tandem OLED. The IPS version was already great. The Tandem OLED is generally better, but often not by that much. It's also a bit brighter. Both are quite a bit better than the normal iPad displays.
I've seen the nano texture version of the Tandem OLED. Reflections are much less, but in brighter surroundings, the image is not that dark. But again, it all depends on the personal lighting situations.
