Ah the Victorian obsession with boiling everything down to pure logic and quantificaion. So Lord Kelvin was basically saying if something cannot be stated by pure fact, measured and calculated it has no validity and anyone who experiences "it" must have next to no understanding of it as it cannot be quantified.
OK, express the following in numbers. The beauty and joy in young children's faces on a Christmas morning. The emotion of seeing sunset over a sea at the end of a Summer day. The feeling and sound of treading on the light dusting of frost on a footy pitch at the start of a local Sunday friendly. Emotions of happiness, sadness, distress and anger. You, I and almost everyone can understand these emotions, knows them, how to achieve them, when, where, how and why yet they cannot be quantified that easily, if at all. Sometimes numbers are nowhere near enough.
Getting back on track, point was that camera manufacturers are obssessed by numbers. Correction, the ad-men working for said camera companies are obsessed by numbers as photgraphy is based on imparting an emotion of something you see and wish to share. You cannot run an ad campaign that says, "Our latest XYZ camera will impart better emotion than ever before!". It's meaningless and for comparison to a competitors product, utterly useless. So they grasp at straws and use the camera's stats as a selling point, but the numbers up to a point, are utterly meaningless. It's almost always down to the ability of the fleshy thing holding the light box that makes good and intresting pictures, understanding the use of light, tone and composition, but those are not things that are easily measured and quatified for ad campaigns.
