No way to query color of a specific pixel

Unlike pxt-common-packages, there's no way to query a color of a specific pixel.

"In circuit playground, you have a block "pixel color at 0" which returns the colour of that light. Is this block available in micro:bit for strips that you add on? e,g. I want to know what colour light 4 is in my RGB strip?"
