Did the Midland definitions of up/down remain after grouping,

They remain to this day. Changing designation would be a fraught
task, I can see why it would be put off even if it was thought to be
a good idea.

Lines presumably change designation somewhere in Derby Midland
station. Perhaps there is some sort of object which marks the spot.

Also some designations might not be logical with the current railway
map. I don't know if it happens anywhere, but the designations may
have been set originally via a route which is now closed, such as
the former route from London to Nottingham via Corby and Melton
Mowbray.

indeed if you travel from Trent jk to StPan, are you still heading down?

I should have been more explicit. Up to Derby applied to lines not
going to London. The result of this is that a train from Birmingham
approaching Derby is running on the Up Main, while a train from
London, which will end up at the same platform, is running on the
Down Main. Both will depart on the Down Main, according to my 1980
Quail map.
