No, just that sRGB is approximated with RGB primaries and a 2.2 gamma curve vs. the official ICC profile, or using the CalRGB/CalGray colorspace.  Similarly, AdobeRGB can be approximated using its primaries and the 2.2 gamma curve vs. the official ICC profile.  And then there are multiple sRGB and AdobeRGB profiles for different ICC versions...
