Make 3G, 2G, 2G+-Status more clearly visible

[EloquentZebra]

I use my smartphone quite often with a color filter / grayscale mode for not having to much screen time.

In this situation the vaccination / test status (3G, 2G, 2G+) is due to the choosen colors not clearly visible. I guess this is similar for the iPhone Certificate App.

Might it be possible to add something not depending on colors, i.e. e striketrough or something similar?

Here is a sample image of the problem:

This should already be the case. For a certificate of type "test" it should look as follows:

• 3G : cert is valid in under 3G rules
• ~2G~ : cert is not valid under 2G rules.
• (2G+) : cert is valid under 2G+ rules, but only when combined with a second cert of complementary type.

In your examples it is similar: The left is "2G+" since it seems to be a recent-enough vaccination - thus it is valid in 2G+ on its own. The right is "(2G+)" or "maybe 2G+" since the vaccination is too long ago - thus it is not valid in 2G+ on its own.

I hope this clarifies it. Also note that you can tap on this "3G 2G 2G+" field to get a full description of the validity. Any suggestions on how to make this 3-way distinction clear and consise are of course welcome!
