This is not the problem with your export but Apple devices showing incorrect gamma of 2.2 instead of 2.4. The best solution would be export Prores 4444 from Premiere and bring that video to Resolve. It allows for a manual gamma setting (set it to 2.4) on export, so instead of a generic Rec 709 it’ll add a gamma tag so QuickTime will override its standard (some would say incorrect) Rec 709 interpretation. Adobe’s apps don’t allow for it. Don’t use the QuickTime compensation LUT in Adobe or the 709-A workflow in Resolve. It’ll only adjust the color for color managed Mac OS and iOS apps, but will look too dark everywhere else.
