I was actually referring to the claims (made in these forums) that diffused reflected light illuminating an eink reader screen is different to other diffused light (such as that from a backlit diffuser such as in a tablet). In fact visible light photons are visible light photons regardless.
Reflection may change polarization and will difuse the light, but LCD displays, for example use diffused light anyway.
With regard to the reflections you are thinking of it should not be a problem. First with any half decent display it should not be an issue even with non-matt glass. Reflections will be visible if the device is off or is asleep with the screen to black but that is of no consequence.
There is another reason why with half decent displays on small devices meant to be used at hand held distance reflections, should they be visible, should not be an issue is that that the optical distance from the eye to the text on the display is only half the optical distance to the reflection. At normal handheld distances the human eye is not capable of focusing or concentrating on both at the same time.
