Yes, but a picture is worth a thousand words. If the products packaging is highly misleading (making a kiddy pool seem far larger than it is, for example), a picture outside of a photo studio will show this fact quite readily and obviates the need to examine the product in further detail.

I still find photos helpful because they show what the product looks like in real life. How bright is that laptop screen really? An few indoor photos from different people is helpful here.

You have no idea what the exposure settings were on the camera or the amount of available light. It isn't possible to judge screen brightness from uncalibrated imagery.
