Juan... Tom has been very helpful to others who have questions about the murals and lighting. He had me paint one... and he has actual experience. He is very nice to help out. I can say anything I want, or think people want to hear... so I appreciate when Tom, and others, have given their suggestions.
OK, let me try and answer your new post.
I am thinking that your Grafik Eye and rope light are great for your room (if you were planning on having them there anyway. I love rope lights and have painted in many theater rooms that had them. There are really cool things that can be done with them. But, I really wouldn't expect much from them as far as charging the paint.
Can you tell me a little about your soffit? Is it close to the ceiling? Is it a foot or more down from the ceiling? How far does it extend out from the side walls? If it comes down even 7 or 8 inches down... you could put in a couple of black lights up in there, with the rope lights behind them... and you are set. You could probably even set them up on either a switch or a remote.
If the soffit is not that low, you still might get away with getting some black lights up in there, though it might be tough.
Since it is only a 7 x 7 area where you want the stars to be painted... is it out of the question to have a black light in a nearby closet, or behind a chair... or under a sofa, that you could pull out, turn on for 10 minutes and then put away? That would keep costs down to about $30 (if you get an extension cord to go with it) and your ceiling will shine just like you had lights in the soffit.
Now, if you wanted to see stars during a movie... then you'd probably have to have the light on during the movie. In the picture that you included in your post... that customer has the perfect set up. his soffits drop down about 2 feet and come out from the side wall 3 feet. And, on the inside of the soffit it is on an angle. It starts at 2 feet down (in the front) and angles to about 4 inches below the ceiling at the back. He then put in 13, 4 foot black lights. When he has a movie playing with the lights on, the stars are very visible, but not overpowering. I was there watching a movie once and I asked him to turn the black lights off so that I could see the difference... and the stars were still visible and beautiful. Without the bluish or purplish (I'm colorblind) cast from the black lights... the stars were just as real as outside. And, for the remaining hour or so of the movie... most of the stars were still visible, though not as bright as when he first turned out the lights.
Now, to finally get to another of your questions.... the lights that you see in that picture are only from the black lights. He has no rope lights up there. You just notice the brighter lights around the edge of the ceiling because that is where the black lights are.
And, the black lights really don't brighten a room up too much either. Maybe Tom can answer this better if he reads this... but when I was watching the movie with the black lights on, it really didn't affect me, or bother me at all. And, as you can see... the customer in that picture has a lot of lights around the room.
My suggestion for keeping costs down is to go with any lighting that you already have planned for the look that you want to achieve. Then, if you can fit a couple black lights into your soffit... then great. If not, then have one nearby that you can bring out for a few minutes.

Although it's been forever since I've played with black lights and I can't recall whether they actually do cast much of a visible glow.
I assume the effect below then was accomplished with both black lights and a bluish rope?
I'm wondering if something like the following would work well if I pair the rope and UV lights into a single zone?
Zone 1: Main lights (side wall & screenwall cans)
Zone 2. Audience task lights over seating
Zone 3. Rope / UV lights
Zone 4. Accent spots behind AT screen aimed at LCR
