It’s most likely me, but have the BBC blocks been made bigger on the idents? Admittedly I haven’t watched BBC One on tv much recently so there may not have been any change.

I don't think they have changed.  It would be rather difficult to do anyway, because of all the other elements within the idents such as objects passing in front of the graphics. It would be like making them all again from scratch that very few people would notice. You'd also then have to change the ones on the promos as they wouldn't match.
