My walls lean a bit. I haven't measured exactly, but there's probably a difference of about 1 cm. Can I still install shower doors? Should the aluminum rail be screwed in so that it hugs the wall, meaning slightly bent, or should it be completely straight? (which means there will be gaps between the wall and rail in some places). I assume the latter is better to ensure a door that slides correctly in the rail. I'll have to insert some washers as spacers where there are gaps.
The model by Duschbyggarna with a full rail can accommodate differences of up to 12mm when it comes to crooked walls.

A little "leaning" wall can be handled by the shower wall's mounting rail. A "banana-shaped" curved wall, however, is another matter. In that case, one might have to partially build up as you write and then conceal the gap with grout.
The two shower walls I installed, the rail felt stiff/rigid so not easy to "bend" I would think.
