They are rated the same from Porsche.
Many ROW markets did not have cats, however.
Non-cat coding makes for completely different ignition and fuel mapping.
In good tune, I'd guess ROW S4+ make more power, overall.

Since in most places you'd need cats for inspection there really isn't much pratical difference.
There were lighting equipment & function differences of course and some markets (RHD) had different airbag configurations (1 vs 2) for same year, some other minor feature differences but its hardly consequential. USA cars tended to be all configured fairly heavily as 'standard packages' while quicker delivery in Europe means there are more option variations there, probably less true of ROW cars delivered further away.

Depends where in RoW
As far as power/engine, the actual brains themselves are the same - its just the coding plugs which differed for non-cat, cats with, and 91-octane (RON) w/cats.
Aussie S4's all have cats (Oz requirement since 86), but also had a different coding plug due to lower quality fuel here in the 80's - the 91-octane pin, which enables different fuel/ignition maps to US or other RoW cars and allows use of 91-RON fuel (equivalent to your 87 octane in the US I think? here pumps have 91/95/98 RON).
For US owners, its possible to swap your coding plug for a low-octane one with no other changes. If you want to run the non-cat maps, you also need to add a bridge to the O2 sensor connector and add an idle-mixture adjustment potentiometer.

A better question would be whats the difference between Pre-87 MY Euro & US...?? If and/or when I buy another Shark I want to get a the correct MY Euro with highest HP/TQ without modifications.

80-82 "Euro" 928 - 4.5L K-jet but with higher compression (10:1) than 78/79 models. rated 229hp.
80-83 "Euro" 928S - 4.7L k-jet rated by factory at 300hp
84-86 "Euro" 16V 928S 4.7L LH2.2 (known as S2 in the UK and lately here) - rated by the factory at 310hp
86 "Euro" 32V - 5.0L LH2.2 - lower compression version of the US '85/86 motor, rated by factory at 288hp
There's an outside chance you might come across a Japanese 85/86 - they were the same engine as the USA cars, but will have a VIN starting WP0ZZZ.
Note *all* 928S in '86 sold outside North America have the S4-style brakes/suspension (i.e. there is no "86.5" outside the USA).
Good luck finding an '86 S2 in the USA tho'..

Canadian cars although very similar to US models have subtle differences with their standard options.
Cars up here came with heated seats and no rear a/c for obvious weather reasons. My GTS although VIN is coded as a 93 MY was actually sold new in 92 in Montreal. My car also has daytime running lights, mandatory in Canada using the fog and dash lights but not the rears which was achieved through different relays on the main electrical panel.
Lesser changes are language related; French and British English vs American.

I currently have the 86.5 / 5 Speed and it is the CAT's MEOW!!! Absolutely LOVE this car for all the obvious reasons and being PORKENIZED its a blast to drive!
