My wife has ambient lighting in her 2020 Highlander Limited and it refers only to a faint blue strip along the dash and doors (plus door-handle lights and white exterior "HIGHLANDER" puddle lamps). Again, not adjustable, brightness or color). 😕

Are you referring to the thin strip of faint white lighting under the wood accent pieces on the doors and dash? In my 2019, it's not color-adjustable (I don't even think it's defeatable). I've been through the manual front to back and couldn't locate any option to do that (though it would be nice to have). I've no other ambient lighting save for the exterior/interior door handles and footwells and none are adjustable. I hope you find what you're looking for.
