The Artillery Spotting increase from the Shiun is negligible. +2 extra Fleet Line of Sight compared to Type 0 Obs or OS2U. There's no reason that LoS has to come from a seaplane, either. Any LoS from ship or equipment gets added in to the total.

The only important thing for seaplanes is that some experiments have shown a (possible) slight difference in Double Attack chance (-2% to +2% modifiers when using the Type 0 Recon as a baseline). It looks like more testing is needed before any definite conclusion is reached. Doesn't look like any testing has included the Shiun in this specific test, so the most logical assumption is that it is equivalent to a Type 0 Obs or Seiran, while keeping in mind there is still the possibility it gives a slightly higher bonus (if the whole seaplane bonus thing is in fact solely LoS related) or even a lower bonus, due to the lack of solid information.
