I would assume untagged images on the web to be sRGB
http://www.w3.org/TR/REC-CSS2/syndata.html#color-units -- "All RGB
colors are specified in the sRGB color space"
Most images on the web are untagged. Even major art museums supply
untagged images to the web. But I would assume those images were
converted to sRGB before they were posted to the web. As an example
take an image(it will be untagged) from the Met (www.metmuseum.org)
into Photoshop and assign it sRGB. Then do the same with an image from
a news agency (ap.org, magnumphotos.com). To my eyes (Munsell tested 20
years ago) viewed on an Eizo ColorEdge the color looks more logical as
sRGB than as my display profile.
Are there any Windows browser supporting profiles? I don't think there
is even one. I would think most images for web use would have been
moved to sRGB so that they would look good to Windows users. They just
don't look right in Safari.
(Apple's web images seem to be "Apple RGB" although they are not tagged
either.)
Would not the use of the display profile be counter-logical, as only
local poorly built images would display as intended, leaving the vast
majority of images to display incorrectly. It seems counter to the
current standards used for web content.
Am I wrong... I have tried to understand correctly --not wanting to
waste people's time, or embarrass myself.

Safari assumes untagged images to be in the space of the default
display's profile. This is the same behavior as Preview, so the nice
thing is an image opened in Preview looks the same as an image opened
in Safari, whether it has an embedded profile or not. If you have
multiple displays you can set which one is the default using ColorSync
Utility. Assigning any profile to untagged data is always a guessing
game since you have no idea what the creation environment was. A case
could have been made on either side of the issue, either assuming sRGB
or assuming the display's profile, basically a no op. I imagine the
choice came down on the side of assuming the display's profile for
untagged data in order to have a unified behavior with other cocoa
apps on the system.
