When I look up thick thunderbolt 4 cables I see a bend radius of 2 inches at most. And my very thick 15 foot 4K displayport/HDMI cables came packed in a box with a 3 inch bend radius. You can manage a 3 inch bend radius with a quart bag, let alone the 1 gallon or 2 gallon bags that I'd expect to act as reasonable cable storage.
