Do not underestimate good old CRT's. Even my almost 20 years old EIZO
CRT monitor was better in terms of color reproduction than my current
high-end TFT - and for that I really miss this heavy 45kg monster.
An important design issues for sRGB was to get maximum quality while
using only 8bit/channel for encoding - color banding gets already much
more prominent within Adobe RGB and 8bit encoding.
Also sRGB takes an "ideal" viewing condition into account i.e. dim
daylight surrounding and images viewed on a dark gray background - what
Firefox meanwhile does but Thunderbird, Chrome, IE still do not.

Well, as mentioned I can meanwhile switch to 10bit/AdobeRGB and do so
e.g. for viewing all the shots taken with my digital camera (always
using raw format output). And for some kind of images (e.g. a series of
night-life-shots taken in Tokyo) it makes a huge difference, especially
in the green-cyan to green-yellow range.

Not to my knowledge. But I might be a bit out of business and do not
know the current state of e.g. OLED technologies - not using phosphors
at all ;)
