Zigbee2mqtt revisited: No more ugly transformations

This is a long and useful topic! This may be more of a Zigbee2MQTT question but how do we find out all the available options that something like a Hue RGB bulb has?

I am used to my Xiaomi sensors and sockets which seem to broadcast their current status. Am I right in saying the HueBulbs don’t broadcast their current state and settings?
