Chris,
The issue isn't gamut size, it's where certain hues land inside the
gamuts. Find an image, like the red bridge reference image, with a
vivid blue sky in it, duplicate the image, then assign Generic RGB to
one and sRGB to the other. You'll notice the sky is much more purple in
sRGB than in Generic RGB.

Chris,
I never said the Generic RGB Profile was larger than sRGB, I said it
was different and didn't suffer the same problems.
John, you wrote:
"Generic RGB Profile.icc is the profile used for untagged RGB images.
Its primaries allow for blue skies and red apples."
Your statement directly implies that sRGB primaries do not allow for
blue skies or red apples. However, sRGB primaries do allow for blue
skies and red apples.
That Generic RGB is overall smaller in gamut than sRGB, and your
assertion there are colors (blue skies and red apples) that exist in
Generic RGB but do not exist in sRGB, appear to be incongruent.
