Is adobe RGB the full range of SML lotus projected using previously mentioned transformation?

I'm curious as to why sRGB was selected as a common standard in displays. Is having a higher gamut too expensive? I can't see it being that much different than constructing a sRGB display.

Why is it possible to convert an color in AdobeRGB into sRGB if sRGB cannot represent all colors in AdobeRGB? How does this convertion preserve the original color?

It's interesting to note that sRGB's color gamut encompasses just 35% of the visible colors specified by CIE, whereas Adobe RGB encompasses slightly more than 50% of all visible colors (source).

JPEG images offer the same number colors no matter what color space you use, with the difference being the range of the colors that can be represented. In other words, sRGB can represent the same number of colors as Adobe RGB, but the range of colors that it represents is narrower. Adobe RGB has a wider range of possible colors, but the difference between individual colors is bigger than in sRGB.

Also sRGB is extremely standardized. Most browsers, applications, and devices are designed to work with sRGB, and assume that images are in the sRGB color space. At this point, the complications and issues associated with AdobeRGB far outweigh the slight increase in color range. However, AdobeRGB is still popular for printing professional images!

Since the color representation is not linear, why are we using the triangle for the colorspace? Can we have some non-triangle colorspace?
