If it mattered it would not be "direct from stick", but rather mixer output. With mixes you apply curves, scale factors, offsets, which all have to be calculated. Everytime there is a rounding error that will increase with the number of mixes you cascade. If the calculation resolution is higher, you'll reduce the problem.
However where this matters mostly is in the intermediate calculation stages, so in the radio internal workings (which nobody talks about) rather than on the RF transmission. At least you can hope that a radio that sends 2048 steps will also do it's internal calculations on a 2048 step basis, so with more resolution than one that does 1024.
On the RF transmission I don't think it changes much, I've tested several servos (OK, not the highest end you can find), but they all needed between 2-4us input difference to make a "step". That's only 256-512 steps over the standard pulse range.
So... No, IMO transmitting with a resolution of half an us over RF is mostly marketing talk.
