The apparent grain size of 400UC,as seen through a grain focus and upon enlargement, is similar to NPC or any of the pro 160 films by Fuji or Kodak. Neither NPC or UC is the finest grain film. Reala and Konica's Impressa (my spelling) are finer. I haven't shot a lot of the konica film, but it didn't seem very contrasty. Reala is not very contrasty either until you start to 'over' expose it. Warmth can be achieved at the enlarger (set your filter pack on the warm side) or with a warming filter when shooting. I don't know of a neg film that is inherently warm.
