The reason these photos work so well is because the uplighting isn't the focal point. Way too often I'll see uplighting pictures taken by DJs that focus on the wall itself... because to DJs, the wall and uplighting fixtures are what matters.
When you show these off to potential clients, before you start talking about the lighting, ask them what THEY notice in the pictures. Their answers likely won't have anything to do with the lighting in the room. What they'll tell you they see are happy people dancing, a smiling bride and a couple slow-dancing. This is your perfect opportunity... "Yes, you're right - but I also want you to take note of the color along the tent. That's not Photoshop; it's a special service that we offer. Our lighting design adds flair and elegance to the room that you wouldn't get otherwise. Is this something you might be interested in?".
(Adapt the question any way you want...).
