When you get new paint mixed, it is more likely to be slightly different and when you add years of exposure and aging on top of that, you are likely to get some variation. Give it some more time -- even thought paint dries to the touch in minutes, it isn't completely dry for a lot longer. Also get away from it and see if you still see it -- or better yet, have someone else see if their eyes are drawn to any of the touch ups. Clean the wall where ever possible instead of using paint. Then see what you can do to help the places that need paint. If you have a cooperative paint person at your Lowe's, you might be able to get them to help you tweak the paint a bit. You might be able to get a sample pot of a darker shade that you could mix in. I have also been known -- well, not known, but I have done it -- get out my other cans of paint or even craft paint -- those 99 cent little bottles, and mix until I get what I need. Work with small amounts if that is all you need - take a cup or jar and mix a small amount -- working with dots of the tint paints until you get the hang of it. Test on index cards or posterboard, a plain white paper plate. I haven't done it often, but it has pulled me out of a couple of cracks. Also, use a small craft brush and only fill in what is essential. Another trick I use when touching up is to feather the paint out. sometimes adding a little water or using a wet brush to thin the paint as it goes over the existing paint. That is more likely to work on your living room paint (lighter color) than the red, but I've never tried it on a strong color. On the red, I'd be inclined to put the photos back up if the nicks don't show - change out the pictures in the frames if you are happier with that. Even if you repaint, there will be new spots that need retouching when you move your things out. I've bought two homes thinking I wouldn't have to paint most of the rooms only to move in and need to paint everything. Worst case, if you feel you need to paint the LR, get the color as close as you can and let the break of the white and wood stairs provide the break you need to stop. And if you do repaint anything, leave them the leftover paint for their move-in touch ups.

I agree, Ben Moore Revere Pewter : ) In my living spaces, I use flat paint, in bathrooms & kitchen I use semi gloss. If you are concerned with a 3 year old child and fingerprints, consider using an eggshell finish in your living room. It's not as shiny as semi gloss, not as matte as flat. You will be able to wipe off those prints easily.

Not a designer by far, but I am familiar with these sorts of cozy spaces (which I actually love, but they can require some creativity!) The problem is the "dining area" is also a bit of a hallway from front living room to kitchen, front front entry to rear entry, from back to stairs, etc. Usually this "hallway" will occur closer to the stairs by the wall. Having a bigger table there and chairs can clutter up that area visually and functionally on a day to day basis. If usually it is just your husband and you day to day, I wonder if perhaps a bench seat by the opposite wall to the stairs and a small square or rectangular (either one being expandable) table (plus a couple chairs) may be best for day to day to leave it a little more open for moving about, and then if you are entertaining you can expand into that extra space and add more chairs. Do you have a basement or storage area you can keep extra chairs/leaf extensions for a table? These are kind of benches I am thinking of. You can certainly do a movable one, does not have to be secured. I think either a straight bench or a L shaped bench would work as you have that bit of wall by the kitchen:
