Brezza vs Venue ground clearance: does that 3mm even matter on trails?

Saw a spec comparison on Spinny listing Brezza ground clearance at 198mm and Venue at 195mm. On paper that gap is nothing, barely a coin's width, but every time I take my Brezza over broken forest tracks I wonder how these numbers are even measured, laden or unladen, with full tank or empty. Anyone who has driven both back to back on the same bad stretch, does that 3mm actually feel different underbody or is it just a number on a brochure?
