Well Apple obviosly could do that. Remember Mac Air news? When installing windows, it actually gets brighter and equal to Macbook Pro 13. Well one of the selling points of MBP13 is the 100 nits increased brightness over the Air. So Apple limited the brightness for well known reasons.
Remember Apple telling that it has no access to your devices? Well when Apple stores were robbed, all of the Iphone/macs were blocked(even though it was new in the box models so no icloud) and message appeared to return the item to the store until the police were not called.
Apple obviously has wide and long reach hands - store models can be brighter for sure to attract people. But obviously, that bright mode run in the store is not safe for casual people - people will complain about "burned OLED panels" in their iphones.
