Yes the SOMA value is the one to use. The Treasury Direct somaAccepted value is the amount the SOMA took when the auction of that treasury occurred but does not reflect any purchases the FED may have made from their dealers post issuance. For example. cusip 912828TJ9 were 10yr UST issued back in 2012. FED didnt take any at auction but purchased a bunch since then (without looking it up Id guess during bazooka QE in early 2020).
