Small changes really do make a difference! It’s way too easy to get lost tweaking values.
Nice work on these! I’d say #3 is the strongest. One thing you could do to help with the light from the bathroom is move it left or right so that it doesn’t line up perfectly with the bed sheet and and potentially increase the values just a little so that there’s a nice rectangle of light spilling across the bed and wall. Aside from that I would increase the strength of the sunset a bit as well, which will in turn bounce more light around the room. While it might not seem very bright in person, I bet it would still seem more powerful than the lamp.
Hope that helps!
