This is where I am going to jump in and point out the differences I see between Brian's LA and Betsy's yellow lilies:
Brian's NOID LA lily has a fine brown pencil edge on the petals and they appear to face upward. It is more "bowl" shaped unless Brian can tell us they open up more.
Betsy's lily lacks the pencil edge, has fewer spots that are closer to the base and opens wide. The area around the nectaries appear to be lighter than the overall tepal color. Or is it the lighting that makes it look lighter? Both of Brian's lilies look solid yellow all the way to the base.
Brian's Home Depot lily does look similar but the spots are larger and I think (not easy to tell from the angle of the photos) that his blooms are concentrated closer together with Betsy's having a more open form.
My 2 cents...
