Can anyone please explain to me what happens "inside" a slot machine when an operator decides to change the RTP? Does the paytable change? Do the probabilities of the combinations change?
If I'm not wrong I have seen par sheets with "set" RTPs where it's either 96% or 94% or 85% (random numbers) depending on the particular probability/paytable combination, but what if one wanted to have some custom 92.76% RTP? Is this possible or are slots only settable to these preset RTPs?

When some websites state the RTP range of a certain slot (for example 92%-96%) is it just gathering sources from online casinos or does it mean that it's impossible to find anywhere in the world that same slot with an RTP lower than 92%?
What about Cleopatra here https://wizardofodds.com/games/slots/cleopatra/ ? Does this analysis only pertain to this specific version found at the specific site or is this for all Cleopatras in the world?

Thank you

It depends on the specific machine, but is often the probabilities that change. Other things that can change are the following:

-Paytable
-Free Games Reels (which would be the probabilities, essentially, only during Free Games which would cause them to return better or worse)
-Progressive Meters-if applicable. (This is the amount of each bet that increases the progressive(s).)

In theory, a slot could be designed to be capable of more or less specificity, but generally speaking, a given slot title is only going to have a handful of RTP settings.

On some occasions, slot games might show an RTP range if the amount that the player is betting is a factor. A player can sometimes be eligible for certain jackpots or features on greater amounts bet than lower ones, or maximum lines played as opposed to fewer than maximum. Otherwise, it could just be that the probabilities of certain events are different with higher bets.

It's the same thing with Video Keno. You might provide a range for all of the possible bet amounts and spots picked for a particular title---but the specific return of the game would depend on how many spots the player is playing and/or what bet amount the player is playing. Denomination can also be a factor with different types of games.

Please note that this post consists of generalizations and is hardly comprehensive.

I'm not a slots expert, but I suggest the way RTP varies can differ widely between manufacturers.
In a couple of cases, I've seen it done by simply modifying the number of free spins from a scatter round, from 6, 8, 10 or 12. I don't think changing the paytable of a typical slot is common.
Changing probabilities is likely, and for many slots that would be inconspicuous. They just win or lose more often with no obvious reason.
Here in the UK, slots have to show the RTP on the front panel.
Psalm 25:16 Turn to me and be gracious to me, for I am lonely and afflicted. Proverbs 18:2 A fool finds no satisfaction in trying to understand, for he would rather express his own opinion.

Are there any well known slots for which it is known that there is only one or a couple of preset RTPs, possibly on the higher range?
What about these lists? https://www.casinolistings.com/software/igt is this just for online slots?

I have a bunch of slots-only freeplay and don't want to burn it on some 85% game.

I always like making my games just change in the bonus rounds. It is also more economical as every paytable has to be proved by the regulatory commission which of course charges by the hour. Another advantage of that is a patron can not tell by playing the game which version it is.
At my age, a "Life In Prison" sentence is not much of a deterrent.

All this and more. You may have overlooked payline configuration for multiline reel games; what counts as a payable pattern (and what does NOT) combined with the order of symbols on the virtual reel configuration could possibly make it's less likely for certain combination wins to land. Changing from 5 line to 9 line to 12 line to 15 line to 20 line to... all changes the math; some patterns will make 4 symbol wins harder to land, some easier, due to partly coincident paylines.

Assume that someone buying a slot machine can get whatever RTP they care to pay for. I believe there are some people around here who have designed custom reels for slots to meet certain customer requirements.
May the cards fall in your favor.

Usually the number of higher-paying winning symbols changes. I've been meaning to compare the reel stripping for a 95% game compared to a 85% game, and I'll post the results.

For physical slots, a machine comes with a menu of RTP settings. Cleopatra is an old game and has a more primitive-looking operator interface, but its menu is essentially the same as at the 4:20 (heh heh) mark in this video:
