ooohhh I just checked ... you are right ! anyway for old pictures, the Exiftool or photolab9+FilmSImulatioPack are still necessary.

OH! I hadn't even noticed that the dial had moved from S! Thank you! 🙏🏼 This is something I hate about this camera - this dial moves on its own, you can't fix it so it doesn't move onto a different setting! 🤦🏻

Reala ACE has been available on the X-H2S since firmware version 7.0

I noticed some of what you are describing, but in my images, the difference seems more related to the body than the chosen simulation. Images from my X-T10 are slightly more yellow tinted than the ones from my X-T30 or X-T30 II (or the newer bodies have slightly more neutral auto white balances than the older one does if you want to think of it that way). I shoot raw and use Provis as the base simulation in all of the bodies because it is so neutral to start with, I can tell during a quick image playback if I have over-cooked an exposure.

Please forgive me for not being more specific… ”The DRIVE SETTING button gives you access to burst shooting, bracketing, single frame, Advanced Filters, and more. On the X-T3, Drive functions are set using the top-plate dial under the ISO settings dial.” https://www.fujifilm-x.com/en-us/quick-start-guides/quick-start-guide-fujifilm-x-t3/ HTH.
