It's not Adobe RGB at all despite recent claims from Samsung marketing, but in case there's interest here I shall develop that in another thread.
It should potentially have more gamut in saturated shadows than AdobeRGB, which is desirable for those who are making prints, as that's usually the part that LCD is lacking. I suppose all LCD desktop, laptop, TV and mobile displays will be replaced by OLED in near future (and conventional projectors with laser projectors).
As for the srgb-centeric wet mini lab printers, all newer Noritsu since 37HD series can automatically recognise and print correctly AdobeRGB rendered images, large format printers like Chromira etc. have classic ICC colour management module, and all Frontiers have easily accessible mode where you're not limited to sRGB rendered content. Wet mini labs will be replaced by dry (dye based inkjet) in future, with more gamut than Endura/DP2 c-prints and ability to print from any colour space.
Oh, and BTW any 100$ desktop inkjet printer can "handle" AdobeRGB (and any other colour space) renderded images, and usually have quite huge gamut, far beyond sRGB.
So much for sRGB-like devices - sooner or later they'll gonna share same fate as ColorMatch RGB Apple Trinitron CRT displays.
