An image, saved by Photoshop as EPS can have an embedded (tagged) profile
(choice in the save menue). In Illustrator this EPS retains its profile
if the whole EPS is embedded and it loses the profile if the whole EPS
is linked.
My tests (which can be easily replicated) show otherwise. If I place an EPS raster file (saved in Photoshop with a specific embedded profile) into Illustrator, its profile is not honored, meaning that the placed image's appearance is incorrect -- since it conforms with the default profile *in Illustrator*, not with the one embedded in the raster file itself (whether this is linked or embedded).
If I save that Illustrator file as a PDF (v. 1.6 or 1.7, with "Include all Profiles" checked), the profiles embedded in the EPS images files are still *not* honored (judging from their incorrect appearance -- actually, there is some unorthodox behavior in *linked* EPS images).
On the other hand, the PSD and TIFF formats, as you mention, always look correct, in accordance with their embedded profile.
Bottom line, the EPS format is to be altogether shunned in color managed workflows, as either inadequate or unreliable.
Nowadays there is no reason to use EPS.
Agreed. Unless the separators specifically demand that it be used, for any reason -- in which case one should make sure first to separate the file for the intended output profile.
