Rick - part of that dullness may be due to the dye - not sure what you used but if it's a commercial leather dye you should buff it well with a clean, dry cloth before adding any kind of finish.
Commercial dyes are basically a powdered pigment suspended in a liquid carrier (i.e. alcohol, toluene, etc) and when the carrier evaporates off it leaves a fine residue of the powder which will leave a dull finish and will also rub off if not removed prior to finishing - thus the need to buff well.
A commercial version of a PC finish is Montana Pitchblend - a mix of beeswax, mink oil, and pine pitch - and one of my favorites and after 48 years being in the leather crafting biz I've tried about everything.
Otherwise if you want to stay as PC as possible you can make your own dubbin - which is a mix of tallow or lard (NOT Crisco, but real lard), beeswax, and oil - the oil can be olive oil, mink oil, neatsfoot, or cod liver - bear is great if you can get it.
One mix I use is 5 parts lard, 5 parts beeswax, and 1 or two parts extra virgin olive oil, depending on how thick I want it - melt together over a low fire or use a double boiler, por off and let cool. Apply in LIGHT coats, let absorb, and buff with a dry cloth for a low gloss satin shene. FWIW - OVER oiling leather is one of the worst things one can do - leather is best at 18-22% "oil", more than that and it can and will breakdown the cell walls, leading to damage.
As noted there are many more finishes from traditional (i.e. Hubbard's Shoe Grease and Sno Seal) to modern hi-tech (i.e. Resolene).......
