I know this thread is a few weeks old, but since no one posted a solution:
I just solved this issue myself: things appearing different in Photoshop than they do when I save them.
What to do:
View => Proof Setup => Monitor RGB
View => Proof Colours (On)
Then what you see in Photoshop and what you see post-save appear the same.
