So I tested the latest pre 2.3_4 build. It's pretty tough ilumination since it's all indirect, top downlight are above the ceiling, and the wall lighting is done with linear tube fluorescents hidden in the ceiling and in the floor washing the inside soundproof paneling and showing thru the wood panels.
I set too warm light (2400k) but I like the results.
Feel free to comment and complain

No retouching, just downsized from 5000x5000 to 1250x1250, rendered for 168 samples and took about 1h30m
