I will chime in and state I agree with the OP and find it odd where a room or enclosed building is sold in the marketplace, that if the vendor made their own lights and posed their characters for their promo images why those light sets and or poses aren't included. Saving off light sets takes seconds. Poses not much longer. If they used a purchased light set and or pose set then it is easy to list in the credits the name of the light set or pose set used.

If clothes or shoes are sold and the promo is V4 or Dawn posed in front of background, the lack of details doesn't bother me.
