That quote is on under features on the article for the original Pebble, right? Might be that the Pebble 2 used a different screen; I can't really find info on that though.
Regarding the Time, I think the product page for the new Time 2 specifically says how the curved screen lens on the Pebble Time wasn't that good.
Edit: Found the quote under the Core 2 Time section
Flat glass lens (less glare and reflections than Pebble Time family curved lens)
