Odd that nobody has filed a reproduceable bug like that with Photoshop.
We've seen claims like that before, but every time it was a misunderstanding
on the customer's part.
Are the screencasts and example files enough or should I file an
"official" bug report? (did you ever try to explain a mess like this in
a reproducible way in few words? in a tiny web form? in a foreign language?)

2.) Some profiles seem to trigger Photoshop's
scene-referred-to-output-referred compensation by mistake.
The profile has to be marked as scene referred before ACE will treat it as
scene referred.
We have seen several calibration tools incorrectly mark profiles as being
scene referred when they were not.
All envolved profiles (including the monitor profile) are ICC V 2.x.
There is no ciis tag as far as the eyes can see.
Then we need examples for Manish and his team to examine.
A bug report would be good, or you can just email them to myself and Manish.
I don't have Manish's E-Mail address, but I filed bug reports. See below.
3.) Even though the "compensate for scene-referred profiles" setting
seems to be part of the Color Settings File and hence should be
synchronized across all CS applications, it can cause inconsistent
results. Either InDesign and Acrobat simply ignore the setting or they
are not "bug-compatible" with Photoshop.
Only Photoshop and After Effects use that option, as documented.
Apparently the bug is linked to Photoshop's "compensate for
scene-referred profiles" option. The only way to get consistent and
reproducible results with the profiles I mentioned is to deactivate the
option.
Yes, if the profiles are bad and triggering the scene referred processing
somehow, then they could cause problems in Photoshop and After Effects.
4.) The PDF/X-4 Preset in CS5 is buggy: The embedded profile is based on
FOGRA39, but the Output Condition Identifier is "FOGRA27".
Again, file a bug so we can fix it.
If you don't tell us about bugs, they won't get fixed.
I just filed a bug report concerning the PDF/X-4 preset.
I filed 3 more bug reports relating to (a) Photoshop's Color Settings
Panel (b) wrongly triggered scene-referred profile compensation and (c)
inconsistencies between Photoshop and other CS5 applications in therms
of the "compensate for scene-referred profiles" option.
Have a good weekend :-)
