No. Invoice has signature for whole invoice. Of course, only payee signature (fee of this channel is fee from the peer of the payee, e.g. hub). Payee has incentive to give accurate information about the channel. Otherwise payment may fail if the channel fees or CLTV-delta, is not same as wanted by the peer of the payee. So only payee signature should be enough; if payee gives bad information about this channel, payee loses on getting paid.
