I'll see if I can get the filler to look ok first... I'm not too precious about the floor, we've got a toddler who likes colouring it in.Better option may be to remove said tile, find reason for the crack and replace with a new one.
I think the reason for the crack is just a fault in the tile combined with the UFH. It's a very fine crack, not really noticeable unless you're looking for it.
