Correct, it will not show until you sync the block that has the transaction.
I created a channel to Boltz|CLN (see Amboss), then created inbound liquidity by creating an invoice on Aqua wallet (they use Boltz for LN - L-BTC swaps) and paying it through my node.
Yes, I received my Ocean payout! ⚡⚡ But it came on a different channel. 😃
