Hello Tom and all,
Sorry for my honest words:
1) Display profiles in mobile devices:
The idea, that a display profile should be managed on the OS side and
needs an API, so that an application can read, the current valid display
profile is nothing that needs a discussion with vendors and users.
********
These are ICC colormanagement basics, which are implemented since 15
years or more in Windows and Mac OS and a little less years on LINUX /
X-Server.
As an ICC member I expect, that the ICC-leading team makes a clear
statement on this topic now !!! There is nothing that need to be
discussed about !!
********
------------------
2) security issues
I also don´t understand why images with embedded profiles are not a
security problem in mobile devices (laptops) with Mac OS X or LINUX, but
are a security problem on mobile device with iOS or Android, which are
derivated from Mac OS X and LINUX.

3) Working with two color manged displays
You are correct, that the problem of working with two colormanaged
displays is not easy to solve from the technical point of view. But this
problem is more typical for Labtops with a second monitor and quite
untypical for mobile phones and tablets.
Best regards

Hi Jan-Peter
Do you agree that it makes sense, that at at least iOS and Android,
should have a central place for a display profile, which could be sRGB
as a preset and a also ICC compliant CMM which would be available for
highend Apps and ignored from standard Apps ?
Do you also agree, that the ICC should recommend this functionality to
Apple and Google ?
The whole reason that we (the ICC) are trying to formulate this meeting is
to discuss these issues with the platform and web developers. Before the
ICC can/should recommend any functionality, we need to understand the
physical problems that surround the Web/mobile environments and the real
needs of the consumers.
With regard to the security issue that I am talking about, if the profiles
aren't interpreted or read, they are not an issue. They just take up space.
I'm running some tests on popular browsers to examine colorimetrically, the
nature of the data handling. At the moment, display color management is an
issue in nearly all of them, just like the OS situation. This is a
situation that I would like to see cleaned up on the platforms, but there
are a lot of technical issues on the browser side. A very simple example is
the need to handle a tagged element that spans two different displays. It's
not an easy problem to solve.
Regards,
Tom
