- Comparison reveals significant variations among fifteen sRGB matrix profiles, challenging the original goal of eliminating color management.
- Profiles differ in white points (D65 vs D50), tone response curves (standard vs gamma approximations), black points, and RGB XYZ values.
- ArgyllCMS sRGB profile is identified as the most accurate, being color-balanced and normalized, aligning with sRGB specifications.
- Practical consequences include potential color shifts in saturated cyans/greens and tonal differences due to TRC variations.
- Color.org profiles with non-zero black points and simplified gamma curves can cause issues like shadow crushing in conversions.
