Is the weight difference between folding ebike models actually noticeable in daily van life?

Looking at a few options and the weight varies quite a bit between what gets described as lightweight and standard models. On paper the difference looks small but I have read a few comments suggesting the lighter ones feel completely different to handle in tight spaces and when lifting in and out of the van. Wondering whether this is a genuine practical difference for someone in their 60s or whether it only matters at the extremes. Anyone who has used both and can compare honestly?
