I would guess that maybe there's an overhead by adding additional NAND Channels? I wonder at what point the performance suffers because you have to split everything into too many channels?

The NAND channel count within SSDs is usually limited by a combination of the host interface bottleneck (no point in using 64 channels if 12 is sufficient to saturate the uplink) and by the cost of increasing pin count on the controller (a current 32-channel controller is a 1517 ball BGA). Increasing the channel count also adds to the power draw, and most products try to stay within 25W maximum.
