Thanks for the feedback. Based on the more details I thought you are actually correct. The Lido Charts are generated by software internal process from the Lido NAB db stored in their computer, which is their 'raw data'. Seeing the DCT missing in their description is a particularly nice find!
For future reference, the Lido NAV db has a tabulated format (Excel like) which you should be able to check with the Flt Ops team at your airline directly, without the need to second guess the cockpit display and your memory of aircraft behaviour. Then compare it directly with AIP coding table.
It was a pleasure reading about a pilot who actually cares what the computer is doing and understands why it shouldn't. To my experience, men of this character are overall fine aviators too, nice to share the same online space.
