QuickTime...sucks.  Just don't use it if you don't have to.  For online work, you don't have to.  MP4 is the standard these days.

This is not a problem with the media, it's with the players used or system settings. From LONG experience dealing with this sort of thing.

PrPro works in and exports stock-standard BT(Rec.) 709 video files ... 0-255, stock gamma, period. This is sRGB by international standards. It sounds like what you're viewing it through ... the player and/or your monitor ... are using a different color space and gamma setting.

Some monitors may be in other color spaces, say A-RGB, P3 (I think it is ... ) ... or something else. On such a system, it is likely that PrPro produced media looks different "outside" of PrPro if the player used does not on it's own work in Rec. 709/sRGB space settings.

QuickTime player is notorious for this. And many of the included 'system' media players do things to "enhance the viewing experience" which simply muck up the imagery.

I would suggest first checking your monitor's color settings, and if at all possible, going to sRGB and calibrating with a puck/software setup. Some useful ones are available for under a couple hundred USD, and while not perfect, will be useful for most non-broadcast needs.
