From my understanding, the CT5V-BW uses the same LT4 from the CTS-V. Not like the CTS-V was low on power, it had 640 hp in 2016 already so this iteration is a small power bump. The S63 saw bigger changes than what you're implying lol and the part number literally reflects that (TU being Technical Update). F10 S63B44T0 -> F90 S63B44T4 - many changes were made that you can look up.
Just easier for BMW to offer cookie cutter specs by limiting transmission choices since they have like 30 cars in their lineup.
