I am not in your league in the knowledge of the game but your CG swing looks a little unusual.
The most obvious is your bent arm. Also, it looks like you have shifted your head quite a bit to trail side on the back swing. You must have exceptional peripheral vision if you can still see the ball at the top of the back swing. Your chin SEEMS to be more pointed down. This is not recommended in a CG swing except Stack and Tilt (fundamental) causing your shoulder to bump into your jaw rather than going under. I also noticed that you have a slight "sit down" motion on your down swing (a Tiger move).
I would say the reason you hit it "dead straight solid" is because you may have above exceptional athletic ability.
I see that in both of your swings, you keep your trail foot planted at impact. May I ask why? I have been working on this a little because I tend to spin out a little.
BTW, the sky is blue and the grass is green
