particle physics - What are the average matter, antimatter, and binding energy composition of protons and neutrons?

For a free baryon at rest at room temperature, how much of its ~1Gev (rest) mass can (on average) be considered as matter, as antimatter, and as binding energy?

For a baryon in a nucleus, I assume this will also depend on the intranuclear pressure. Please, references, if possible. Note the related question 13809

Motivation: I have read that the uud quarks in a proton say correspond to less than 1.5% of its ~938 Mev rest mass. I am asking about the remaining >98.5% of its rest mass. I would have naively assumed that it splits 50/50, but that is apparently wrong. Also, I have also read that all of the remainder is all binding energy. But that has also been contradicted.
