Get COB strips, good ones are essentially dotless.
You'll still have the contrast between the strip and the background, though. You have to hide the strip in a clever way, there are all sorts of hacks and decorative elements out there. However, that's also why all stuff done entirely with LED strips looks kind of cheesy, there's always a visible gradient. Designing it without gradients is the tricky part, and it usually means you need spotlights and other types of sources for the main lighting.
