I have the original H2O, IR touch. It's whiter / better contrast on ambient light than:
  • PW3
  • Flush PW4 (slightly poorer PW3)
  • Original Libra (slightly better than PW4, similar PW3)
  • Flush Sage
  • Flush Elipsa
However the other are all fine. You need them side by side and the difference is not enough to show up easily on honest photography.
I'd struggle to see much difference between recessed Libra (original), Flush Sage (later N778, not 1st N777) and Flush Elipsa.
The Sage N778 and Elipsa seem to have the active screen in contact with top layer, no bezel shadow at any angle. The photos I've seen of the N777 review Sage seem to suggest the display is slightly below the top flush layer as a shadow is visible.

Comparisons with front light on don't count, so you need good ambient light to compare as the front light doesn't entirely turn off on the Kindle PW3.

Obviously older ereader screens (I have or had all of Nook Simple Touch, Sony PRS-350, Sony T1, Kobo Touch, PW2, Kindle Basic (no light), Cover Story) are all a bit poorer or a lot poorer. The DXG uses a newer screen to DX and so does KK3 to KK2. I have those two and they are not as good as H2O original, but not bad because there is no touch layer. Older screen models are a lot greyer.

So some flush screens may be poorer, but some may be similar to recessed capacitive screens.
The IR H2O is certainly poorer to use for touch, but it may be implementation or CPU speed rather than the technology. Traditionally before ereaders existed it was lowest resolution, capacitive next and resistive far better, but not as good a digitiser.
A system for a digitiser stlyus can lie behind the screen, but needs an electronic stylus (though some have no batteries and can get power from the gadget, though that is poor for battery life on eInk)
