Yes, you are of course right, technical limitations have had reasons in the past to use suboptimal solutions if we're talking about coloured pixels in CRT or LCD displays even but in today's world with our display technology there's no real reasons to use those other than personal preference. About the photons, you could look into a regular paper sheet's or book page paper's albedo values and compare that to the light emitted from a led display, it's not even in the same ballpark. Why do you think people enjoy reading on an ebook reader rather than a normal tablet with a lcd/led display? Artificial light strains our eyes way more than normal sunlight (or even indoor lighting) reflecting off of surfaces indirectly lighting everything for us.
