The TFA theme wasn’t conducted by Williams this go around. He was busy with other parts of the score and entrusted it to a friend of his. Which is why it sounds so off. Here’s an article about it.
I think that’s only a part of it (important to note that Dudamel conducted the end credits too). It definitely sounds like certain elements are favored more in the TFA recording than in others, those this could easily come down to the mix as well. I would say it sounds “off” due to a number of factors, mostly the mixing, the different orchestra and everything that goes along with that (players, instruments), different recording techniques, and the simple fact that we got used to the other recordings (and especially the TPM one).
