My concern with these is that for commercial use, they're generally designed to be brighter and more eye-catching, so it's hard to get that "picture frame" look like the Samsung Frame has when it's in standby mode (I still honestly don't know how they do it because I've experimented with all the backlight/contrast/other settings on other displays and it doesn't look anywhere near as good, whereas with the Frame, people are often legitimately surprised that it's a TV). I'd also assume that commercial applications also aren't interested in low power consumption. Some of the "digital signage" displays I look at are like 200W where the Frame claims a 0.5W standby.
