Not at all.  The BOM cost is not in the noise, but it's one of the smaller factors for a product like this (sales numbers in the thousands per year, not millions, with high NRE costs).  As something of an example, I do high grade security stuff, and folks that make EAL4 and up secure elements won't even talk to you until you're in the 100k of volume and at that volume you're a one-off.  They can't sell you unit quantities of chips even if they wanted to, because you can't afford the NRE.  When you're doing 1M+ of volume, that's when your NRE is spread across significant units and when BOM cost starts to be of primary importance.

If anything, it reflects how much of a bargain it is to buy the smaller bandwidth version of the same scope.  All the same engineering had to go into the product.  All the support costs are the same.

This is amazing!!  I wouldn't do this myself, but just wow!

I won't go into sales details, but for basically every line of scopes all the way up to the top, we sell a lot more of the lower bandwidth models than the higher bandwidth models.

That is at the point of sale I guess, but what about the BW upgrades? How many of these lower bandwidth ones end up getting a BW option?

The gauntlet has been thrown!  OK next level mod is to take this thing to 1.2 or 1.5GHz!!

electrolust:
Can you characterize the response curve?  My memory might be bad, but as I recall from the literature, the sub-1GHz models have gaussian response and the 1GHz (as shipped from Keysight) has maximally flat response.  Apologies if the posted traces show that fact, I'm a bit excited and haven't read through in detail!
