I have a GLSL sampler1D uniform variable as a look up table but I get the impression from the compiler that it doesn’t support sampler1D.

Would be new to me that Unity has a Texture1D class and without that it makes no sense for Shaderlab to support it as you can’t feed it with anything kind off.
There are only 2D textures in unity (be it render texture, movie texture or texture2d), but nothing prevents you to have a 128x1 texture for example. or if you have multiple lookup textures for one shader 128x2 or x4
