Pale Lager
The color of pale lager ranges from light bronze to nearly transparent and the alcohol anywhere from 4-6%. Adjunct usage may be quite high, though in some cases the beer is all-malt. Carbonation is typically forced, though not always. One thing that does not vary is that neither the malt nor the hops make much of an impression on the palate. These beers are brewed for minimum character, though faint traces of hop or malt may show through. Commonly detected features and flaws include fusels, oxidized malt and skunked hops. The body will often be thin and/or spritzy while the finish is typically mildly bitter.

Premium Lager
A beer that straddles between the mainstream Pale Lager and Pilsner. Not all beers that call themselves Premium Lager are, but those that are will typically have a deep gold to light bronze colour, and distinct influence of malt and hops. They should be free of adjuncts and will have a softer carbonation than Pale Lager or Classic German Pilsner. IBUs will typically range in the 20’s, and lagering times will typically be 4-6 weeks, more in line with what pilsners have. Overall accent will be malty-to-balanced, alcohol in a slightly tighter range than either Pale Lager or Pilsner (4.5-5.5%). Most often the product of a microbrewery or brewpub, but macrobreweries can make this style if they jack up the hops a bit and make it all-malt.

Not seen that it is a requirement for “pale lagers” to have to use adjuncts, while all all-malt beers sjall be “premium lagers”.
Certainly not how Swedish admins have treated the two styles.
As per above “who cares”, that can be said of about quite a few beer styles, that some/many users of ratebeer feel really should have a style of its own.
Just because many active raters on ratebeer feels lagers that does not taste of IPA is an inferior beer to start off with does not mean all “pale lagers” should be clumped together by default.
By example the style guidelines we use for Swedish homebrewing judging have 13 lager sub styles, not including the “others” category. It does not contain what is sometimes referred to as “international lager” with plenty of DMS, since the ones deciding the style guidelines feel “just because a lot of commercial brewers have managed to convince customers it shall taste of DMS, doesn’t make it less if a flaw”.
When I judged at WBC earlier this year, not counting what is called “hybrid/mixed” there are some 26 lager styles mentioned.
Just to point out there just might be different types out there, also for lagers.
