Luma is basically half of the S-video signal so you won’t need to worry there, it’s 75 ohm consumer standard.

For your NES, if you add the resistor and it was outputting 75ohm all along, the OSSC won’t be able to sync (most likely it will try and the LCD will keep flickering). In that case you can probably assume it was 75 ohm and remove your resistor… though really, testing on a scope would be the best way to tell.
