Why are Korg grand piano sounds +5ct at 440Hz (~441–441.5)? I know about spread, but wouldn’t you prefer 440Hz to be exact? C4 is +1ct, so maybe they just center the tuning along that.

But it’s nice to verify that a good default for spread is something like +5ct for C4 and +7–10ct for C5, with a larger increase for the very upper and lower octaves.
