Export for iphone comes out a different hue...Any suggestions?

Hey FCPX users,
I am trying to put out some quick tutorials on Instagram, b ut my video from FCPX to iphone changes hue dramatically...Any suggestions on what to do? Exported for either apple devices/computer/web hosting
If i send the image or video from iphone to mac the colours change back to how the mac views them. So i am assuming its an iphone display thing?
Is this a setting on my iphone? The video has less reds/vibrance in it on my iphone. It's more of a dull/yellow vibe.

I'm not sure I understand what you're asking here, so I'll try to summarize.

1. You're creating content on your Mac with FCPX
2. This content looks fine on the Mac
3. When you view the video on your iPhone, you see a color shift.

Is that correct?
