This is happening because you haven't correctly set the full color management settings before doing the color work.
Checking Color Management settings is now a required regular part of all editing workflows in Premiere.
As there are many different things any particular user could want or need Premiere to do, these days, they've given us (finally!) an updated and pretty near full set of controls for user management of color.
For your needs, you have HLG media ... hybrid log gamma, a form of HDR (high dynamic range). It uses probably the Rec.2100 color space standards. And you can work with HLG media, and export for either HLG to stay in HDR, or have Premiere transform the color space and dynamic range to SDR/Rec.709. (Which is actually what I would recommend still.)
Color Workspace/Lumetri Panel/SETTINGS tab, the one named Settings.
To start, you should have your color management settings for display color management, auto detect log, and auto tonemapping all on, regardless of whether you choose to work in HLG or SDR/Rec.709.
Rec.709/SDR output/export
Set the Sequence working space to Rec.709, then do your color corrections. Use only SDR/Rec.709 export presets. The ones that do not have HLG or PQ in the preset name. This will work except for the mess that Apple made by not using the correct display transforms in displaying Rec.709 video in QuickTime player, Chrome and Safari browsers.
HLG HDR output/export
Set the Sequence working space to HLG, and then do your color work. Use only export presets with HLG in the preset name.
Do the above and your work will have the correct color management within Premiere.
And there isn't any fix for the mess Apple made on only their computers, but only on the Apple computers without Reference modes.
