Does True Wealth receive kickbacks or retrocessions?

No, True Wealth does not receive any kickbacks or retrocessions.

In general, it should be added that passive (i.e. index-based) ETFs are less affected by this issue anyway, as they usually have low total expense ratios (TER) that leave little room for retrocessions. Moreover, ETFs are bought and sold directly on the stock exchange, where no issuing and redemption commissions are incurred.
