Yes, except none of the hemes in your body are realistically going to be unbound.

Hemes each bind 4 oxygen molecules, and the bind cooperatively, so each successive oxygen molecule is harder to strip off. This makes it less likely you have a completely unbound heme while there is another one with four O2s attached.

In your inferior vena cava you'll see usual O2 saturations of ~75%. It can get down to ~55% in the coronary sinus, but nowhere near 0 in a physiologically normal state.
