Yeah there's definitely that aspect too. Though nowadays, led lighting is so efficient that you can get a lot of brightness on reasonable wattage.
That's not enough for the light to feel natural though, you also have to have the parallel rays. And then there's also challenges with brighter lighting to set it up so it's not uncomfortably bright in your field of view or blinding you :-)

It's not that eyes are adapting to low light so much as the fact that exposure to 10k lux stimulates the release of neurotransmitters which prevent the eye from growing too quickly. Last I checked, the recommendation is for children to spend 2+ hours per day outdoors in sunlight. Morning and evening aren't sufficiently lit so it really comes down to school and after-school care scheduling enough outdoors time.
Meanwhile home lighting is well below the 500 lux range, if not even in the 100-200.
