What happens if you skip heart cinematics?
Solution 1:
It's been a few days, so I can finally say this with confidence, and Ross Ridge confirmed:
The Wiki is wrong.
I was only at 6 hearts when I viewed what was considered the 8-heart scene, and only got the 4-heart scene (according to the wiki) upon reaching 8 hearts. So it would seem that you are able to view the scenes in any order, so long as you have enough hearts to view a scene.
