Well technically during the twilight right after the sun has disappeared below the horizon, or just before the sun appears from under the horizon (when there is no direct line of sight to the sun), the sky is strictly blue-er: the reason the sun and the neighboring angles in the sky appears "yellow/orange" is because green and especially red scattered less through the atmosphere, while a good portion of blue light scatters much more easily on our atmosphere, allowing non-line-of-sight blue illumination on land where the sun has not yet risen or where the sun has already set.

All of humanity has been a witness to these observations and yet we blindly assume blue light filters must have such and such an effect.

But even if it did: suppose a modern concrete-cave-dweller has an out of phase shifted day/night pattern with respect to solar rhythm, having blue light as the last form of light actually seems more natural!

Regardless, the intensity of blue (for that matter, all) light is going to be much lower after the sun sets.

but that kind of intensity doesn't really permit useful interaction with a screen

The amount of red light goes down, (and you can use a camera with white set to sunlight to check how much blue it gets on a clear day, it isn't an illusion at all) so if anything, we should be using red light filters, not blue.
