Therefore you don’t benefit from avoiding US withholding tax by investing synthetically, just that you forgo the benefit of after tax dividends (whether they’re automatically reinvested or distributed).

I've had a cursory look with one pair of ETFs, actual 5 year history would support that there is negligible overall benefit after costs. But in theory, as outlined above, there is a benefit to be had in theory subject to the vagaries of tracking error for the physical ETF and a sufficiently low cost for synthetic.
