On this page you will find several different types of sRGB profiles, with information about their intended use.
The sRGB v4 ICC preference profile is a v4 replacement for commonly used v2 sRGB profiles. It gives better results in workflows that implement the ICC v4 specification. It is intended to be used in combination with other ICC v4 profiles.
The advantages of the new profile are:

The user would then convert the data to printer specific values with the sRGB v4 profile as source, the v4 printer profile as destination, and selecting the perceptual rendering intent, as shown in Fig 2.

The three available rendering intents of the sRGB v4 profile should normally be used as follows:
Advice for caution
Ideally the ICC v4 profile should not be combined with ICC v2 profiles. If that is unavoidable, see the intermediate-level ICC White Paper 26 'Using the sRGB_v4_ICC_preference.icc profile' for additional information and recommendations.
The sRGB v4 profile will in some cases not produce the same results as would be obtained using an sRGB v2 profile. Differences will depend on the particular sRGB v2 profile and rendering intent used. See the intermediate level white paper for additional information and recommendations.
Summary Overall users can expect to get better and more consistent results using the sRGB v4 profile versus the sRGB v2 profiles. More details are available in White Paper 26.

Display class version
This profile aims to preserve the appearance of the sRGB display when transformed to other colour spaces. More information is available here, together with a link to download the profile.
An ICC version 2 (v2) sRGB profiles is provided below, with XYZ black point scaling to zero. This 'black scaled' profile has the preferred rendering intent in the header set to 'perceptual'.
The profile contains the standard linearized Bradford D65 to D50 chromatic adaptation tag (this tag was often not present in older sRGB profiles), and the media white point tag is set to D50 (as is required for ICC v4 display profiles). This avoids the inappropriate color casts that older sRGB v2 ICC profiles sometimes produced when the absolute colorimetric intent was used.
The profile will work correctly when either Black Point Compensation (BPC) is on in the CMM/application, or the other profile transform to be used for the conversion is also black scaled. Black scaled profiles are needed when BPC is desired for the conversion but the CMM to be used does not support BPC. Most v2 sRGB profiles in current use are black scaled because they are intended to be used as the source profile in conversions where the destination profile perceptual intent will be used (v2 perceptual transforms typically include black scaling).
