The LG quote, notably, talks of rollable panels -- not rollable TVs.
The utility of the former is completely clear: You wrap panels around things that aren't flat, that's got a lot of commercial (and art?) uses.
The utility of the latter remains non-existent. The market for people who want to sit and wait for a TV to unfurl -- especially one that's as small as 60 inches -- when you can otherwise just have it go on is incomprehensibly small. Especially since this mythic TV would need an encasement that still hangs on the wall.
On the other hand, the transparent design has interesting lifestyle implications. If you coupled it with a second active layer behind it that wasn't transparent when on, you could have a TV that would disappear into the wall when off. Turn it on, the backing layer goes black, the OLED goes on and the TV magically appears.
The uses for transparent in HUDs, displays over mirrors, and numerous other applications are very real. They will make poor TVs unless they can be coupled with a second layer because the magic contrast of OLED goes away without the backing. But that doesn't render them less useful for a lot of other things.
Rollable displays have the same reality vis a vis TVs. It doesn't remove other use cases. And, for what it's worth, a fascinating use case for a high-flex OLED is readily clear in our mobile world. If you could "unfold" your device to double the display and then return the "top half" when not in use and do this seamlessly, reliably with a thin rigid backing and a clever hinge, you could double mobile display area on an ad hoc basis when you need it. That's powerful as smartphones, phablets and tablets become the primary digital tools.
There's a saying about "everything in moderation". If only it was applied to well, you know...
