sRGB is a red herring here. There are colors outside the sRGB gamut, but those colors are all very saturated. "Gold", including the color of the actual metal, isn't saturated enough to be among them. The real problem is that gold is a mirror. It's shiny and changes appearance based on viewing angle and environment. A computer can only simulate that for the scene within the computer. It can't make the image itself more or less shiny than the physical monitor. Without the shininess, gold just looks like a dirty yellow.
