There is another perspective here. First, it is known that Eisov (who represents the spiritual world of ‘Tohu’) is only the firstborn regarding to the external dimension whereas in the inner dimension it is Yaakov who is the firstborn.
With this we can explain an inference from the words of the Alter Rebbe’s ‘Torah Ohr’ on the words of the Possuk: לְפָּנָּיו מַלְאָּכִּים יַעֲקֹב וַיִּשְׁלַח “Yaakov sent messengers ahead of him” to לְפָּנָּיו מַמָּש a place which is actually ahead of him—a higher level than his own which is the level of the early kings of Tohu.
Seemingly the intention behind the words of the Alter Rebbe לְפָּנָּיו מַמָּש means to imply something better, which would mean that Yaakov sent angels not to a level equal to himself, but לְפָּנָּיו, to a level greater than himself.
However, according to the esoteric understanding of RaShi’s explanation of the Possuk: וַיִּשְׁלַח יַעֲקֹב מַלְאָּכִּים לְפָּנָּיו, that this means מַלְאָּכִּים מַמָּש “literally angels”, is translated to mean that Yaakov only sent the physical substance of the angels, but the spiritual dimension of the angels remained with Yaakov which transforms the word מַמָּש in this instance into a derogatory term.
This would mean that the term לְפָּנָּיו מַמָּש is also to its detriment.
All of this means that the fact that Eisov (who represents the spiritual world of Tohu) is before him, meaning higher than Yaakov, is only in the מַמָּש which is in the external material substance yet internally Yaakov himself is the higher.
