Looks like I'm looking at everything through a yellow filter.
Check and see if Night Shift is turned on, and if so if the Warmth is turned up all the way. You can ease it back if you don't like it.
Yeah I've tried fiddling around with True Tone, Night Shift and even the Colour Filters under Accessibility options. I do find turning these all off does bring the colours back closer to where I like, but still leaves a slightly warm hue and not exactly my 6S Plus LCD.
Though I can probably live with it. I'm loving everything else about the screen. Thank you for the help :)
