They have gotten better. Recent consumer projectors use triple (RGB) lasers as a light source, which improves color accuracy a lot. It's not worth replacing one that works, but it is noticeable.

My experience with laser projectors, is that they work great, but have very weak beams (for reasonably portable ones). I need it to be something I can toss into a backpack (along with a bunch of other stuff), and be around 1000 lumens. Not just lumens, either. The color needs to be good, the resolution needs to be (hopefully) greater than 1080p, and it needs to be usable in a semi-lit room. I don't care about speakers. I use projectors as a speaking aid. I've been using a tiny InFocus LCD unit that's great, but a little anemic (1080p/750 lumens). The promise of a laser, is that you can project it against a cinder-block wall, and it will stay in focus, and show great color.

  I've only used larger, higher power ones that are meant to stay in one place. Even with those, all the "point it at a wall and it looks like a TV" marketing is fiction. They don't look good without projector screens unless you're in a dark environment.

    Makes sense. I have heard that laser projectors don’t need to be focused. Is that true?

      Yes and no, but mostly no. Nearly everything advertised as a laser projector uses the laser as a light source for a normal DLP/LCD/LCoS setup, and needs to be focused the same as with a light bulb source. Even the triple laser ones work this way-the triple laser part just means they don't need a color wheel. There are true laser projectors where the lasers go directly to the projection surface. These are called Laser Beam Scanning projectors, and they don't have to be focused. They work pixel by pixel in scanlines kind of like a CRT, and since the laser doesn't diffuse over short distances, it's never blurry. Unfortunately, it's a dead technology. I only know of one still in production, and it's 120lm or something.

They improve color gamut coverage and color volume, but I would not say accuracy. It's much harder to get an RGB laser projector accurately calibrated than an old mercury lamp or even single blue laser / yellow phosphor projector.
