The visual accuracy of sRGB defined images

I need to establish how many users are disatisfied with the image fidelity
of sRGB / ICC profile defined images.

I believe there is a fundamental over-simplification in the use of Gamma to
describe device / image characteristics, and that there is a conceptually
simple alternative that is much more accurate.

Does anyone out there need it ?
