This really isn't a color management issue, and you don't mention what program you're using or what file format(s) you're saving to.
Sorry for not mentioning the software. As for the colour management issue, sorry, I must have misunderstood the meaning.
I am getting used to this "forum style" one post at a time so please forgive any faux pas I might commit.
I am using Illustrator CS4 on a Dual 1.8Ghz PowerPC G5 Running Mac OS X 10.5.8.
I've come across a similar issue though, about a year and a half ago on a PC running XP.
i don't understand very well,maybe is better that you try again,try to see if working your pictures in filter and gone to light effect ,open this to material
effect,try to move the slider on the left and move to plastic direction...maybe is only a little light adjustment issue.(ps4 for this is the same of ps5).
