The right lighting to see where I need to add some joint compound.

In the middle of the night I can see slight bulging on some seams. Now in broad daylight I can't see them at all. Any suggestions?

You will probably have to decide how much this bothers you and determine what you can live with or you will go nuts. When are you and others going to be in the room? If during daylight hours, you might just leave things alone. If you are going to use the room after dark and with artificial light? Then I guess you have to be a bit more picky.

Those halogen worklights held near the surface with you looking across it can help. Don't start things on fire though. Those bulbs get hot.

Get a halogen work light and hold it close and at an angle to the wall and you can see the imperfections

"Critical lighting" is a drywall man's worst enemy. Sounds like you have a light(s) that shines directly on the joints you're seeing. "Down lights" (cans) are often an issue as they project the light in a direction. Any halogen lighting is even worse. They are more direct than everyday sunlight or most surface mounted, incandescent ceiling fixtures that "wash" the wall with light. Paint with any kind of "gloss" also exaggerates the issue. I've seen issues with "sunshine" causing the problem when a swimming pool reflects the light into the house (intensifies the light) and all of the joints show in the room. IF the lighting is the issue, even skimming the joints will likely not solve the problem. The finished joint is actually smoother than the paper face on the drywall and lighting will show that difference. The only thing that will solve the problem is to "glaze" coat the entire surface with compound, sand, and repaint (called a level 5 finish). Just my guess....
