Nolan films with no DI but still have DCP

[Paul Bartok]

How did the films like TDKR and TDK, INCEPTION etc. get a DCP (4k in the case of TDKR) if there was no DI, did they scan the 35mm Internepositive

or at what stage did the scanning occur to produce the DCP

 

These explain how the IMAX and 35MM prints were made:

But nothing on what stage the DCP was done, I must be missing something lol

It sounds like the scans of the 4-perf 35mm anamorphic OCN done for the blow-up to IMAX and the scans of the 15-perf 65mm OCN made for the reduction to 4-perf 35mm were used / combined to create a single 4K DCP, if I understood that sheet.
