All "laser" papers are aimed at having short exposures and being "scanned" by the travelling light beams. Therefore, they also tolerate some degree of "re-exposure" by overlapping light beams that are wider than the scan and also they tolerate R/G/B sequential exposures well.

Other that what amounts to a different latent image keeping and reciprocity a given white light (optical) and laser paper should have no real difference. In fact, if you look at the curves given by hrst, you see that in one paper the magenta curve is higher and in the other the cyan curve is higher in the shoulder. This gives more cyan shadows. This means that there is a difference in reciprocity. Also note that the exposure is 0.5 seconds. Laser printers are usually faster than that and optical printers are slower.

So, we cannot make too much of the plots.

As for CA, that has its problems too with white light vs laser printing.

You might consider the fact that the paper that is still on the market from both companies is the paper that sells well. Also, you might consider the fact that you can alter contrast with any color paper using the right methods.
