Nice effect on photos taken with S24

[Grayham]

Since getting the S24 Ultra I've noticed that, when I open Photo Gallery, if I look at my photos taken with my previous phone (S20 Ultra) and scroll to a photo taken with my S24 Ultra, after a second or two, it's as though someone has switched a light on to the photo. It becomes very good and bright as though the sun has come out. Has anyone else noticed that?
I don't know what it is but I like the effect.

Yes, this phone is optimising old photos too.

This is the super hdr effect where the picture that's taken in hdr will brighten up

Thank you for the information re photo optimisation and super hdr effect.
