Andrew, I have GRX levers and Ultegra actuators. It acts as if these are not compatible. The levers on both front and rear will not "pump" the brake pades close enough to the discs so that they actuate with almost no pull. Instead they pull almost all of the way to the bar.

Shimano says yes, compatible. See page C-499 here:

That's a little hard to understand but it appears that all of the actuators are the same compatibilitywise.

They are not.

Changing a flat bar Deore disc bike to road levers means new
calipers, for example.
It showed that the GRX gravel 10 speed was compatible with the Ultegra 11 speed actuator.Should I have looked deeper?
Right, that's what you asked and Shimano says 'compatible'.
Then Mr Merriman suggested, "all of the actuators are the same compatibilitywise." That's not true. The road models as a group differ from the flat bar models as a group.
