Laser IMAX uses a much brighter source of light than is traditionally used in projectors. This means they have a lot more shades of gray between black and white. And that means it can convey a lot more detail in darker scenes that will look more muddled with traditional projectors.
For the same reason Laser IMAX is also capable of displaying a much wider range of brilliant colors.
For movies that expand up to the full IMAX screen height, Laser IMAX projectors can also stretch their pixels vertically so that the picture covers the entire height of the tall screen. (Hint: This theater is where you should see Star Wars.)
For the four Christopher Nolan movies mastered on 15/70mm IMAX film (Dark Knight, Dark Knight Rises, Interstellar, Dunkirk) these stretched pixels are less than ideal. However, except for those four Christopher Nolan movies, "full IMAX" hollywood blockbusters (like Star Wars 7/8/9) are mastered from a 4K digital intermediate that stretches the pixels in exactly the same way. If a movie is produced from a 4K master with vertically stretched pixels, then there is no loss of resolution if it is shown on a 4K projector with vertically stretched pixels.
