Code indentation has been automated away since like 10 years or ago or maybe even more.
Vim, Emacs, Atom, Sublime Text, Visual Studio, Eclipse, IntelliJ, NetBeans can all auto-indent code for you. Combined with linters they can also automate stylistic checks and coding convention.
I don't know anyone who indents code themselves. The editor/IDE does it for them.
Indenting code is certainly not a code review check. No sane workplace should waste a senior developer's precious time commenting about indentation problems during code reviews. It is a tooling check that is part of CI/CD.
Why waste human time on what can be done by a machine?
By the way indenting code happens to be the most basic of code review checks.
