It will only become apparent in poor light.
Agreed. Low-light is mainly where you see a difference. And it can be very handy for sports sometimes - when the light is poor, a stop or two of low-light headroom (translated into usable high-ISO) lets you select 1/500 instead of 1/320, or f3.5/f4 instead of f2.8 etc.

Pics related. Not great shots, but illustrative.

It will only become apparent in poor light. But one more thing for FF is an ability to have am F2.8 with a depth of field of an F2.8 on a full frame. After shooting a wedding where I had to swap primes all the time to get a good depth of field, I can really see the advantage. I would be quite ok with a 16-50 F2.0 though, instead of full frame, or an 18-35mm F1.8 in a pinch. I know olympus made a range of F2.0 zooms. I see no reason why Pentax couldn't take the 28-70mm design and equip it with a focal reducer to make it a 18-50 F2.0 for APS-C. That's roughly how Olympus's 35-100 F2.0 was born, apparently.
So for you, at least, it is the improved low light and DOF which makes the FF attractive. That is a clear and understandable reason especially for a wedding photographer. Thank you for the comment.
