Its a mystery for a long time for me too on this 3.5L Turbo. It was first mentioned in some European forum, Wiki has no info yet on it back then.
Yes, 3.5L lower boost and HP is the same as 3.0TT.
What I am curious to know is, is the 3.5L turbo a 3.5L bolted with turbo or 3.0TT upsize to be 3.5TT ?
Why waste money only to introduce a very low quantity engine and that will make the owners suffer in buying parts.
When I first tried to source M276 3.0TT component in USA, all the website does not show a 2014 E400 as a 3.0TT ( does not exist ), it shows only 2015 being an E400 with 3.0TT.
My engine M276.820 is already a Pariah and confusing when trying to access WIS or EPC due to data collision with M276 3.5L , I can't imagine what a M276.850 3.5TT nightmare will be like for the owner and the workshop.

3.5 NA and TT have both larger bore and stroke, so bottom half will be different. This means block, rods, crankshaft.
Cylinder heads, fuel injection. induction and exhaust may or may not be common between the two turbo variants. Not sure if the combustion chamber for a 3.0TT would match up with a 3.5L cylinder bore.
Make a list of parts, then look them up for a 3.5TT and then again for a 3.0TT.
Turbo and intake manifold would be a starting point for me.

When I have spare time I will take a peek. The last comparison I did was M276.820 vs M276.823 components differences.

MAF location
Could anyone direct me to the location of MAF sensor on the M276 dela 30 engine. I have a 2015 ML400 thats been running rough in neutral and want to see if the sensor needs to be cleaned. Do I have to take the air filter boxes out to get to it ? Thanks

There is no MASS AIR FLOW sensor on this (mine) engine. Only MAP ( Manifold Absolute Air Pressure ) sensor.
