Photoshop :: Tools To Fix Adobe PNG Files And Add ICC Profiles?

I want to submit and use pictures in a lossless format like png, but I've noticed that my colors don't get reproduced as vividly when I save in png vs. jpg or tiff because Photoshop (CS5/windows) seems to have broken png support (I guess it gets worse in CS6)... storing color profiles in png's while not widely done, have been part of the standard for over a decade. 
 
Given Adobe's place a providing the premier image editing tools, It's hard to believe they'd not support accurate color in lossless images for the web, but I've yet to see any Adobe produced png that that contains a profile.
 
I do note, that libpng, the most widely used library for pngs, does have the ability to read and store ICC color profiles.
 
Maybe I'll have to write a post processor to add them on... as some programs do read them... and at least once, recently, in reading in a png file, I got a profile mismatch from Photoshop -- indicating that it can read profiles (OR, the file was only named .png, and was actually a .jpg -- if only I could remember what file it was...sigh...)
 
Maybe adobe could release an addon that automatically adds & prompts for profile settings on saves (assuming PS can use them)... Any work flows where people add them?  Does PS read them in properly?
