Hey Hoo-- I'll be there right after you. I'm doing ED on 22 April (LMB E93).
Not sure if it helps, but I had a Topaz Blue E46 (color was only available for one model year before they changed it to LMB I believe), and have observed that LMB is definitely closer to Topaz than IB is. If I hadn't owned one for several years, I would probably not immediately be able to tell the difference between LMB and TB.
