Color Management Problems on iMac 5K (Chrome, Premiere Pro, etc.)

Hey there,

Recently I decided to take the plunge and invest in the iMac 5K. I was very excited about the P3 Wide Color Gamut display only to find that many third-party apps have no color management options and the wide color gamut is actually causing more harm than good. As such, my iMac is operating in the P3 wide color gamut and some apps are running in sRGB, causing major over-saturation and contrast issues in those non-color managed apps. Google Chrome and Firefox, for example, appear way too "vivid," oversaturated, and contrasty as they are not color managed. Safari, on the other hand, I believe is color managed and properly displays colors because it is operating in the P3 color space (to match the iMac display). The major problem that I run into in this is when working with Adobe Premiere Pro. I am a professional video editor that edits videos for a living. There is no current color management option within Adobe Premiere Pro. As such, the app wrongly operates in the sRGB color space and footage appears much more saturated and contrasty on the Premiere timeline than it actually is, leading to a "washed out" export no matter what codec is used. I cannot switch to Final Cut because of collaboration needs, but, for comparison purposes, the footage looks true to what it actually is within Final Cut because, again, Final Cut is color managed. Although it is ridiculous that Adobe has not yet offered color management within Premiere (as After Effects and Photoshop currently have color management), I was wondering if there is any way to fix this on the Apple end until Adobe supports color management within Premiere? Changing the display profile does not change the Premiere Pro timeline footage. To further test, I screen shared my iMac screen with my MacBook. On the MacBook, footage appeared as it should have and web browsers looked normal while they all looked contrasty and overwatered on the iMac - which almost definitely suggests that this is indeed a P3/sRGB color management issue. Any thoughts or suggestions on how to fix this is much appreciated!
