How to not have inspections and language injections in diff? Makes identical code look different

Question

I'm using several of JetBrains' products, like IntelliJ IDEA, PyCharm and PhpStorm. One issue I'm having is that when viewing a diff codelines will look different even though they are identical.

The lines are identical, but the rendering of them are different. That's pretty annoying, as it's hard to spot where there are actual differences.
This example can be mostly solved by turning off inspections, but that turns them off for the whole project, and I will need to constantly enable and disable it.

In this example, there's also no differences. And there are no highlighting from inspections. But still the code is rendered differently. The comment reminded my that this is because of language injections. Turning them off makes stuff look right, but I want them when I work.

How can I make my diff become more readable and the differences easier to spot without all the clutter and without disabling everything?

It's been possible for a while now to change this just for a diff-view. For instance when committing, one can press the cog and change Highlighting Level.
