Color and Gamma in video is a common historical problem. It depends a lot of codec/container/resolution/metadata and of video player/system color management. Some video players can read metadata, some don't. Some video players use color management, some don't. Some players may apply some color matrix correction based on HD/SD resolution, some don't. Legacy QuickTime player read ProRes colors and gamma in one way, modern QuickTime player read in different way. In short - it current reality it is impossible to match exact same look of same video file between all existing software and hardware devices.

In your specific before/after example it looks like incorrect pc/tv levels, or could be due color managed videoplayer in macOS which read some gamma metadata in deinterlaced video and so makes video look too light.
