RTP lobby mismatch?

Been noticing that the listed RTP on the slot lobby screen almost never matches what pops up when you check the paytable or the game info. Not just a small difference either, sometimes it’s like a whole percent or two off. Makes me wonder if I’m playing the “full RTP” or if there’s some special version running depending on the casino’s settings. Most days I just stick to the ones showing above 96 percent, but these mismatches make it harder to trust any of those numbers.

Feels like all the numbers are for the house’s stability anyway, and the only real control is how much you bet or when you walk away. Curious how others decide which games to settle in on with this stuff going on.
