Oh hey, someone better-informed than me.

There's also a sizeable fraction of the reading public of all ages who still prefer print books for a host of reasons both sentimental and practical. (The one I've just discovered: I can't read ebooks before bed because the blue light from the iPad screen keeps me up. Whoops.)

Ebooks have mostly killed the mass-market paperback, though---more's the pity for beach-reading and other circumstances where I don't want to have to worry about the physical condition of sensitive electronics.

Seriously, get a kindle - if you like reading you will absolutely not regret it.

Had a Kindle Keyboard forever, finally impulse bought a Kindle Paperwhite.

Reading even more books than ever, since now I can turn its backlight setting to very low, and it's so much less light than my iPad ever was, while still being plenty to read with, and it's not bright enough to bother my SO if I read while she sleeps.

This. People don't realize the difference between eInk and screens is massive.

I don't know about the iOS walled garden, but more generally there are tools to adjust screen colour temperature to something appropriate to the time of day.

Even if I set the iPad to its lowest brightness, though, it's still about 10x brighter than the lowest I can set the backlight in a Kindle Paperwhite.

IOS 9.3.4b also has automatic temp control built in. I was sideloading f.lux -- but this works just as well.

Definitely try a kindle. It is cheap enough to take to the beach and comfortable in all lighting.
