Man this is frustrating, and even more frustrating, I'm not seeing many people with this issue, so I'm kind of doubtful anything will be done about it.
I got a reply on a separate thread that I made about this issue (before I found yours). He acknowledged seeing this thread as well (although I'm not sure why he didn't say anything on this one), so it looks like we may be getting a fix in the end, hopefully.
I'm still in ME1 but I just started ME2 to check on this and sure enough, it's not the same as when the LE launched as you can see in one of the 4K video on Youtube here, check the 5:06 mark and now my screen caps looks like the ones here. Looks like they increase the contrast and saturation while making the patch.
Mine has looked this way since launch - I thought it was supposed to, but I saw someone on the Nexus mod site has made a fix for it for those of us on PC.

In case you didn't see, Mass Effect 3's fix is up for grabs!
