Sure, and any meal you eat will have a salt content (possibly zero). Doesn't mean that that tells you all the things that could be wrong or right about the meal.
Gamma is just a single element of a color space. The whole trivializing sRGB into being a 2.2 Gamma versus linear is an over simplification that ignores gamut , white point, bit depth and more.
That's my point. You're trivializing what color is because you clearly have not dealt with it at scale.
You can download an alternate color scheme from Technicolor for Canon cameras that makes the colors appear fairly reasonable.
From what color space to what color space, and what display or print type?
Now you're back to describing a average case perceptual color rather than your initial point of accuracy.
