To be fair, the scans of powerless and semi-powerless Superman only show the "mentally regulated" aspect of his power. One could argue that they just mean he can suppress his powers below his normal limit, but don't indicate he can exceed his "limits", i.e. that he can absorb more sunlight than normal. There are, however, other scenes that do show or imply just that.
People who say Superman is just like other heroes when it comes to the dynamism of his power levels are idiots. On the other hand, one doesn't want to go too far and join the idiot crowd by proclaiming that there is some hard consensus on Superman's dynamism, or how it works. There isn't. One needs to be careful and moderate here, sticking to the evidence.
The real underlying truth is that there is a fundamental conflict at the heart of Superman's mythos. On the one hand, a core element of the Superman mythos is the real burden Superman carries on account of his unique power levels. The world depends on him--he is the last line of defense. He has a unique responsibility. And more importantly, the world depends on him showing restraint. If he loses his way morally, or were to be controlled somehow, stopping him would be a huge problem. (His mythos has some strange similarities to the Hulk's when looked at in certain ways.) And part of what makes Superman so good is the temptation he must resist--and thankfully does resist--to simply impose his own will.
This aspect of Superman's mythos worked best when he was the only Superhero. And this is why Kryptonite and his other weaknesses exist. And why people like Batman were given some Green K.
But one can see the obvious problem with integrating this aspect of Superman's mythos into a shared universe, with other top-tier heroes, while preserving some semblance of realistic logic and consistency. None of the above aspects of Superman's mythos really work, or even make sense, when he has peers (or even near-peers) in power. Why do you need Green K to stop him? Just call Wonder Woman. Or if you make Superman consistently and clearly the top dog (but only by a small margin), then just call Wonder Woman, Shazam, the Martian Manhunter, Orion, Black Adam, and everyone else to work together, either put Superman down or save the world when Superman can't.
You can solve the above problem by simply granting Superman a consistently huge power advantage over all other heroes. But this can make him unwieldy for writers. And difficult to add to teams. Still, you could probably write around that, if you wanted. But the truth is that writers don't always want to do that. There are many Superman stories they want to tell that work best when he is at best first among equals.
So comics being comics, writers have for a long time simply ignored the logical contradictions and written the Superman that they want and need for the story at hand. Most Superman stories feature the first-among-equals Superman. But a smaller subset--though a consistently recurring one--of Superman stories features the superhero-to-other-superheroes Superman.
Sometimes, like in the King of the World arc, the clear inconsistency between these two types of Superman portrayals is not explained. However, over the years some writers, likely worried that readers can only suspend disbelief so far, tried to explain the above inconsistency--tried to create a mechanism that allows them to have their cake and eat it to; that allows them to use both types of Superman without there being a logical inconsistency. And that is the root cause of Superman's uniquely fluctuating power levels. At the end of the day, panels in comics are precious and not to be wasted. Words even more so. Writers just want to get on with it, and write the story they want, with the Superman they need. Moreover, no one wants to write themselves into a box, limiting future stories. As a result, the exact nature of Superman's dynamism is rarely spelled out with complete specificity. It's vague by design. And there is no real consensus on even the admittedly vague specifics.
But when all is said and done, there's no denying the fact of what has happened. Sure, other heroes also have their crazy moments where they seem to jump a weight class or two. But these happen far less frequently than with Superman. And with few, if any, attempts to explain and codify the reasons or dynamic. Superman's mythos has relatively unique requirements in this respect, and as a result, --whatever the in-comics explanation (or lack of explanation)--Superman ultimately has a fairly unique track record with respect to wildly varying power levels. That's simply been the case, and I imagine will continue to be the case. There's no denying it, though I realize that this makes for a problematic phenomenon for battleboarders to account for. But nobody ever said writers write to make our lives easy.
