You are totally correct that the dash, and the inside top of the doors, and inside the rear quarter windows are a different shade than the exterior Marina Blue. I have my Marina Blue 67 convertible on a rotisserie right now and am facing the same dilemna. However, it will probably be two months before I have to worry about it.
Before I started this frame off, I painted a new speedo/fuel gauge carrier and the sides of my console with the Bright Blue paint from National Parts Depot in a rattle can. They turned out to be a very close match color wise. However, the rattle can doesn't have the exact same gloss look as the front of the dash. http://www.surfari.net/~scottmoo/interio.jpg
The last owner had repainted the outside Midnight blue and painted the door tops also. But, the dash was never repainted from the original Bright Blue color.
Now, for my frame off though I probably will be taking my glove box door to the local PPG guy for a computer scan. The top of the dash is definitely flatter than the front of the dash. I'm not sure about the inside top of the doors, though, if it matches the flat dash top or the glossier dash front. Maybe someone can jump in on that.
This 1 1/2 year old picture really makes me sad, because the interior really looked great. If it wasn't for all the bondo cracking under the midnight blue and poor previous body work, I'd still be driving it instead of spending all this time restoring it.
