I saw the meam loez, he makes a pretty big distinction between the two. He says that yaakov was afraid because “eisav was living in eretz yisroel and yaakov was living in chutz laaretz”, whereas by kibuv av he writes “eisav was mekayam kibuv av beshlaimus”
He’s careful to not say that eisav was melayam yishuv eretz yisroel, probably for the above 2 reasons i gave. Some sort of zchus, however, there is.
