The one pictured on the right has the earlier type sump with the spacer. The one on the left is a post '15 engine which uses the later Cali 14 sump which doesn't have a spacer.

Were there some post '15 bikes with the earlier set up? Maybe, but I doubt it. More likely if the one pictured is being touted as a '15 or later it is simply old stock that is being sold into a market where the year of registration doesn't reflect the year of manufacture.

In all honesty I don't think the sump type makes a lot of difference. Both systems have advantages and disadvantages. I think the main reason the sump was redesigned for the Cali 14 was because the earlier design was deeper and would of caused ground clearance issues in the low-slung Cali. It's use on the final series of Grisos was likely simply due to parts consolidation rather than any perceived advantage of the newer design.

One thing that the later design does do is diminish the actual volume of the crankcase and given the propensity of even the 1200's to blurt their oil into the airbox I don't think that is particularly meritorious. I do like the sump bottom pick up in the 1400 set up but having said that the earlier bikes don't expose their pick ups like the V11 'Broad Sump' motors are prone to do so it's not something to really worry about.
