Olivero breakpoints have some limitations. There is not a breakpoint for less than 500 pixels. This means that in the first iteration of responsive images in Drupal CMS, the fallback image is not being used as well as it could be.
Only 1x option for screen resolution is included in Olivero.
Add breakpoint for below 500 pixels.
Add 1.5x and 2x options to the relevant breakpoints.
There might have been a reason not to include these in core
We could handle this four ways that I can think of, there are pros and cons to any of them:
1. Take no action for now and don't support it.
2. Raise an issue against core and create a patch.
3. Add a breakpoint file to drupal_cms_olivero.
4. Introduce a Drupal CMS set of responsive image breakpoints.

@tonypaulbarker maybe talk to @mherchel since he is creating a subtheme for Drupal CMS?
