The colours of the PNG file are lighter, less saturated and the

basic colour. See attached screen shot!
Ah, I misunderstood you. Your point is that two renderings in Emacs
of same image file look different. This isn't Emacs's doing,
though. Cocoa is rendering the colors differently depending on the
screen location.
Reverse the buffer/window arrangement (in the setup of your
screenshot, put the startup buffer in the bottom window and the
splash.png buffer in the top window) and you'll get the opposite
effect: it's now the image in the splash.png buffer that looks more
saturated. Put the images side by side and they'll look equally
saturated.
Or view the Splash screen in two horizontally stacked windows...
You can reproduce all this outside of Emacs: Make two copies of
splash.png and open them in a graphics editor, then try moving the
windows around.
Why is Cocoa doing this? I dunno. In any case, this report should
probably be closed.
Maybe it's a "feature" of the LC screen! (For which the Dock is at the
bottom by default.) OK, this old bug report can be closed (hoping that
the NS variant will learn to display the same graphics formats as the
X client or the AppKit client can do)!
