@lucisaurus @swordofodin Thanks for the advice, I have definitely been fooled by my night mode in the past too, but all of my setting look right. I have turned True Tone on, so hopefully this will make a difference.
I went through my past illustrations and noticed that the ones I have the most issues with are the ones that use darker tones and values. It seems very accurate on export with lighter tones...I’m stumped. But fingers crossed the “true tone” will solve my problems.
