I am still a little surprised you are actually seeing something. I understand the concept of what is occurring but the lamp is controlled on both power and ground side. The power side I understand - there is a "wake-up" circuit inside BCM used to sense when a lamp is turned on. I didn't understand the the ground side but maybe there is some internal diagnostic circuitry on that driver which is enough to make your lamp glow.
If you leave vehicle for 1/2 hour with everything off is it still glowing? By that time the BCM would truly have gone to sleep and turned off the direct battery feed to the lamp (leaving only the "wake-up" input active).
Does the dome lamp (when switch in middle position) only come on full brightness when you open a door? I just ask this to make sure you wired new lamp correctly.
The only potential problem would be if your lamp some how "teased" the BCM into thinking a lamp is being turned On/Off. I don't think that is occurring but if you now start running into dead battery conditions I would start looking at your new dome lamp as the culprit.
