How do I correct color differences between iOS and Windows?

I have an arch-vis project that looks beautiful on Windows, and looks blown out and washed out on iOS. All lighting is baked on Windows. No realtime lights, that I know of. The whole thing just looks washed out on iOS though, and I don’t know why.

What can I do, to bring the colors back in line with what I see in Windows?

In this pic, the top is Windows, the bottom is iOS.

Thank you,
