First time dealing with Greenshift/Gamma problem in Quicktime/Safari

I've been editing video on a Mac and in Final Cut Pro since version 2 and this is the first time I've had a huge problem with a shift in color from what I see on the canvas to what is exported - and the first time I've noticed that that problem/shift only happens when the footage is viewed in an Apple program (Quicktime or Safari when uploaded to Vimeo). Opening the footage in VLC or viewing the upload on Firefox? Looks gorgeous. But on Safari or Quicktime? Colors are muted and have a greenish cast.

The footage is for website/computer usage so looking at it on my monitor should be a good indicator. And I've had others look at it and some have commented on the green cast.

So I'm not sure what to do - how best to give it to the client.

Workflow: footage is ProRes HQ, shot in 1080, shrunk to 720 to make 'artificial second cam close-up' (don't ask...). Edited in Final Cut Pro, but I've been going back and forth with it in Adobe Premiere Pro to try and tweak the picture color and contrast, as I've been liking the filters in Premiere better than FCP lately.

I've exported it as ProRes and used Adobe Media Encoder to compress (been using both the Vimeo 720 preset - and tried upping the bitrate, setting quality to max rendering - and the Broadcast 720 preset).

Only time I've gotten it to look good when opening on Quicktime is when I export it as Animation versus ProRes. But as that's 12GB versus 1GB file size (and since compressing it to h.264 makes it look identical to simply compressing the original ProRes to begin with...)

So my question is...what is the best way to export this footage, either in Premiere Pro or FCP, to get the right color cast in Quicktime based computers and non-Quicktime using computers.

I've attached a screenshot of the footage opened in Safari and Quicktime (left side) and Firefox and VLC (right side)
