If a meteoroid burns up high in the mesosphere, how does this affect the visibility of its blue light?

Answer

The shorter atmospheric path length reduces scattering, making the blue more evident.

If the meteoroid burns up high, the atmospheric path length is shorter, meaning there is less intervening atmosphere to scatter or absorb the emitted blue light before it reaches the observer.
