If it is happening on two different surfaces, in two different rooms, with two different paint choices and two different sheen levels...I would say it isn't the paint. There is nothing in common to point to "paint problem". A wall paint is a different formula than a cupboard paint. If it all came from the same can...we might be able to point dirty fingers at the paint...but that isn't the case. You mentioned your husband has a tendency to drag his dirty fingers all over the place...I would start there. These two colours you have chosen may also have a tendency to show oil (body oil, cooking oil, etc...they are all oil) a bit more...simply because of their colour and depth of colour. If different colours had been chosen in the same paint...and no finger marks were appearing then we would know FOR SURE it isn't the paint. It may come down to two things...colour and dirty fingers.

I 'played' on the Olympic paint site with colors. Here are three so you can get an idea- my favorite is the Morning Fog blue hue - ( other colors Peach Statice and Crocodile Tears - tan)

Yes, the brown wall is actually deep purple (aubergine). The carpet is more dark grey than brown. It is not a commercial place, but a large family home, and all the extra chairs are around because we were about to have 22 in for dinner, so the table was fully extended to it's 6metres! (The lounge is totally separate to this room, this is family space, so has the old sofas for sacking out on) But I really appreciate all suggestions and comments as it would be good to pull it together, even when entertaining so many. Cheers!

Black kitchens are beautiful! I would look at your space and make sure you have enough light and space to pull it off, remember that dark colors can pull a room in making it look smaller, also finger prints can be more noticeable on black but i still think it would look great, especially if you have some wood or old red bricks in the space, too cool! Making a Matt black and wood handle-less kitchen shortly in our showroom but not in yet so no photo.
