The shininess of a paint film is referred to as its sheen. It is a measure of how much light is reflected from the surface - the shinier the surface, the higher the % reflectance.
There are no particular standards in the UK paint industry for how to name sheen levels nor what % reflectance a particular name might refer to – each manufacturer has different names and reflectance levels for their paints.
Benjamin Moore paints offer 7 sheen levels for interior paints and 4 sheen levels for exterior paints.

For shinier paints, the reflectance is measured by shining light at an angle of 60° to the paint surface. For flatter paints, the angle of measurement is 85°.
In a room, the amount of light falling on a surface will change how shiny it appears. So, shinier sheens will not appear as shiny in dimly lit rooms as in brightly lit rooms.
