I see similar with a Thinkpad P14s with 7840U. If you can, try powering off the screen and observing power draw. If I haven't confused myself, mine drops down to more like 2-3 watts in that state. As far as I can tell, it is not enabling LCD panel self-refresh. This may be where the extra idle power is going with screen on? If you think about it, it's a pretty expensive behavior to constantly read framebuffer content out of system RAM at 60 Hz.
