Does GC Green come in the bottles with "European Formula" on the front?

So far I have located 12 quarts of green, with two different style bottles, and cam across a couple of quarts of the 0W-30 American version. I realize about the 5010 code and earlier on the back, but if I can skip looking for this by looking at the front label then woohoo.

I also noticed that they are now selling a 5-40 Euro formula that is made in USA, but this does not meet the BMW LL01 spec, but does meet LL98. Interesting - newer formula meets older spec.

Also, I noticed when trying to wash out a couple of jars that I used to take pictures of green and gold, I noticed that the gold was more easily dispersed by Dawn dishwashing liquid than was green. The Gold was held up by the bubbles and did not separate out nearly as much as the green.

Any ideas what this means, other than it is probably a different formulation?
 
Thanks!I have E, H, J (which is looking like it only is GC Gold) and Katrina
