This is too bad -- the Solnet library hardcodes the return format for the transaction to "json", not giving the option to use "jsonParsed". You would need to change this line to pass in "jsonParsed": https://github.com/bmresearch/Solnet/blob/591b814fef270606332da6a4c1da4866f83f07ce/src/Solnet.Rpc/SolanaRpcClient.cs#L432

After that, you'll be able to look at transaction.message.instructions[0].data to get the full info about the value transferred.

Separately, you could also use the preBalances and postBalances to see how much was moved during the whole transaction.
