I’m having a problem where HD videos are using BT.601 instead of BT.709 to display colors.
I’ve tried and compared multiple videos, and the problem seems to be present in both the Apple TV app and the web player, but not in the stand-alone Windows app.
Here’s a couple of examples, taken from the web app:

As you can see, the incorrect color primaries makes reds look darker and more pinkish, while greens are brighter.
