Isn’t this like a ‘sample gradient’ node?
Never used the color ramp node in Blender so not sure

Not quite. This is manual on what it does
https://docs.blender.org/manual/en/latest/render/shader_nodes/converter/color_ramp.html
This is explanation video

But this could be done with a gradient node no?
You make a gradient node, set it to that red/blue/yellow/pink hard cutoff gradient, put it in the gradient slot of the ‘sample gradient node’ and then whatever you want (UV like in that image) into the ‘time’ slot.

Mm… Its does something similar but end result is noticeably different, see abdomen area, i think unity node implementation is different from what blender does.
Here Unity
here is blender

The reason it looks different in unity might be because it uses the red channel of the texture whereas in blender it probably uses the average color or luminance. If you want to correctly sample the gradient you should use a saturation node between the sample texture 2D and the sample gradient node.
