GRX Di2 shifters + RS785 brakes (post-mount)

I've got a 2016 Diverge which is post-mount. Anyone know if the GRX Di2 shifters will work with RS785 brakes? The Shimano compatibility tool says they are compatible, but the spec sheets for the shifters and levers call for different brake hose kits.

GRX Di2 shifter - SM-BH90-JK-SSR brake hose
RS785 calipers - SM-BH59-J-SS brake hose

Anyone using this shifter + caliper combination?
