Are some Omega straps the same with different numbers?

I purchased a 34mm Seamaster Aqua Terra 150m for my wife about a month ago on a metal bracelet. The boutique ordered us two leather straps (deployant) to compare. The two straps are only shown on other watches...
In the web description, this one is brown:

and this one is beige:


The brown one came in first and we went to see that a week ago, and my wife wasn't a fan of it.
Now our salesperson says both have come in, with different reference numbers, but they look the same color.

My wife is hesitant to bother with the trip to the boutique if they both look the same...

Any suggestions? Are the two reference numbers maybe actually the same color? Or maybe Omega made a mistake with labelling?

Frankly, we are surprised the salesperson has been hesitant to figure this out with Omega for us. I am now asking them directly to check with Omega. We just don't want to waste time with multiple visits to the boutique...

Color looks different to me. If it has a different reference number then it's probably different in some way.
