TV power cords; Money well spent, or money wasted?

Hi Folks,

First, A happy, healthy, and abundant New Years to all (where abundant = any tangible, or intangible, that you either need, or desire).

I just purchased a new Sony Z5100 TV:
Bravia 3 engine (whatever that is)
240hz refresh
10 bit panel
TV is networked
Sony N460 Blu-ray

Shunyata SR-Z1 outlet-->Audience au24 "e" pc-->PS Audio Quintet.

My questions: Would it be qualitatively beneficial to upgrade from the TV's stock pc? If yes, have you any suggestions for an appropriately priced pc for the setup that I currently have.

As always, any and all input is appreciated.
Gary
